1
00:00:04,660 --> 00:00:12,500
In this worksheet, we are going to draw the window for the labor assignment.

2
00:00:13,539 --> 00:00:20,519
So on this page, you will find this square, the rectangle.

3
00:00:20,519 --> 00:00:28,899
So this rectangle's size is, you can read it here, is an A4.

4
00:00:28,899 --> 00:00:41,200
okay so and in this case you have the midpoint here and at the bottom already marked okay so

5
00:00:41,200 --> 00:00:52,229
we are going to connect these two points with

6
00:00:52,229 --> 00:01:03,649
a slight line we don't need the whole of it okay so i'm just going to mark

7
00:01:03,649 --> 00:01:17,280
because we are going to need it later here a line and here below

8
00:01:17,280 --> 00:01:31,900
So, just there below, I'm going to mark here just a very soft line, okay?

9
00:01:32,420 --> 00:01:34,959
Because we are going to need later the midpoint.

10
00:01:36,640 --> 00:01:36,840
Good.

11
00:01:37,480 --> 00:01:41,560
Here below, we are going to mark 10 millimeters,

12
00:01:42,560 --> 00:01:50,159
because we need a parallel line to the bottom, to the side of the paper,

13
00:01:50,159 --> 00:01:59,400
at 10 millimeters so if you have an a4 imagine this is the side of the paper okay and if you

14
00:01:59,400 --> 00:02:10,099
have this rectangle you leave 10 millimeters up so we connect these two points at 10 millimeters

15
00:02:10,099 --> 00:02:26,759
that's it and we are going to leave 17 millimeters from the margin this is for a4 okay if you have

16
00:02:26,759 --> 00:02:45,020
an a4 plus you will need 23 okay so now we are going to mark here we are going to mark

17
00:02:45,020 --> 00:02:57,949
From the side of the paper, if you have an A4, you need 17, 1.7, okay?

18
00:02:58,889 --> 00:03:10,349
And on the other side, you will need the same, 1.7, okay?

19
00:03:11,069 --> 00:03:11,710
Great.

20
00:03:11,710 --> 00:03:35,729
now this we will erase this later okay but from this mark at 10 millimeters we need another 13.5

21
00:03:35,729 --> 00:03:48,169
Okay, so from this point up, you need 13.5.

22
00:03:48,990 --> 00:03:52,810
Okay, that is 13.5.

23
00:03:53,349 --> 00:03:57,569
And on the other side, we are going to do the same.

24
00:03:58,189 --> 00:04:08,409
So from the mark of 10, we need another 13.5.

25
00:04:08,449 --> 00:04:30,470
okay great we are going to connect these two points something like that there okay so this

26
00:04:30,470 --> 00:04:45,720
height is 13.5 okay good um anyway the measurement you have on the on the aula virtual

27
00:04:45,720 --> 00:04:50,800
okay on the assignment on the aula virtual you have all the measurements in case you forget

28
00:04:50,800 --> 00:04:57,000
one of them okay anyway i'm going to mark here you don't have to do it on your

29
00:04:57,000 --> 00:05:11,579
on your page but this is going to be 17 or 23 if you have an a4 plus

30
00:05:11,579 --> 00:05:22,889
that is the idea and here you are going to leave 10 that is the idea okay great

31
00:05:22,889 --> 00:05:38,589
so in order to close the rectangle we need we are going to mark again 17 here and 17 on the other

32
00:05:38,589 --> 00:06:01,480
side 17 there we are going to connect everything up and we will close we will close our rectangle

33
00:06:01,480 --> 00:06:21,779
So, you can see here that it's 10 millimeters from above, from the side, from the lower side of the paper, 17 from both margins, and 13.5 total height, okay?

34
00:06:21,779 --> 00:06:33,680
So, this height is going to be 13.5, okay, millimeters.

35
00:06:33,879 --> 00:06:41,500
good so here we have the rectangle once we have that we are going to draw

36
00:06:41,500 --> 00:06:48,740
parallels inside this rectangle five millimeters from three of the sides not

37
00:06:48,740 --> 00:06:54,819
the top one but the other three okay so we are going to measure again five

38
00:06:54,819 --> 00:07:15,189
millimeters on the right side five here below five again here in the corner five

39
00:07:15,189 --> 00:07:40,470
again on the other corner the same 5 5 and in this corner 5 again and here we

40
00:07:40,470 --> 00:07:49,290
placed before the midpoint of the whole segment there that is the midpoint so we

41
00:07:49,290 --> 00:07:55,790
are going to need here on the middle okay we are going to need another five

42
00:07:55,790 --> 00:08:05,360
millimeters column so here I'm going to measure from the midpoint I'm going to

43
00:08:05,360 --> 00:08:21,180
zoom a little bit so I will place 2.5 and 2.5 to each side and there on top

44
00:08:21,180 --> 00:08:31,529
you place a midpoint you can measure if you need and we are going to place

45
00:08:31,529 --> 00:08:47,250
measure 2.5 2.5 there okay so again we have used the midpoints there on top and

46
00:08:47,250 --> 00:08:54,149
And at the bottom, we connect and we place this midpoint and that midpoint.

47
00:08:54,429 --> 00:09:08,980
Okay, so I'm going to outline everything out, connecting five millimeters apart from the different sides.

48
00:09:08,980 --> 00:09:23,509
so you have you get parallel lines five millimeters apart from the previous

49
00:09:23,509 --> 00:09:44,149
rectangle there this one and this one so that is the final appearance of the

50
00:09:44,149 --> 00:09:52,279
first part so we got the previous rectangle and inside five millimeters

51
00:09:52,279 --> 00:10:00,399
five millimeters up five millimeters in and here using the midpoints five

52
00:10:00,399 --> 00:10:09,820
millimeters centered that is really important okay great I have named these

53
00:10:09,820 --> 00:10:16,779
six points with letters so we understand each other explaining the procedure

54
00:10:16,779 --> 00:10:27,559
so right now we are going to draw the two first arches to do that you're going to use

55
00:10:27,559 --> 00:10:38,559
these centers so we are going to need a first so you place a compass on a

56
00:10:38,559 --> 00:10:52,419
and we are going to draw two arches passing through D and C so first couple

57
00:10:52,419 --> 00:11:08,409
of arches go from A to D and then we change to C okay they are parallel and

58
00:11:08,409 --> 00:11:11,250
and they share the same sensor.

59
00:11:12,149 --> 00:11:16,529
Then we are going to switch to D.

60
00:11:17,870 --> 00:11:20,190
I'm going to get a little bit closer.

61
00:11:21,029 --> 00:11:25,549
So I'm going to go to D, place the compass on D,

62
00:11:27,230 --> 00:11:31,429
and you draw the symmetric arc.

63
00:11:31,429 --> 00:11:36,350
And from D you change the radius to A

64
00:11:36,350 --> 00:11:42,019
And do the same

65
00:11:42,019 --> 00:11:47,759
So you will get this first window

66
00:11:47,759 --> 00:11:51,159
You close the first couple of arches

67
00:11:51,159 --> 00:11:57,659
So we have used A for these two arches

68
00:11:57,659 --> 00:11:59,860
Passing through C and D

69
00:11:59,860 --> 00:12:02,500
And D for these two arches

70
00:12:02,500 --> 00:12:04,779
Passing through A and B

71
00:12:04,779 --> 00:12:20,120
We are going to repeat the same procedure there, in the other side, but in this case we are going to use C and F.

72
00:12:20,120 --> 00:12:55,379
So you place the compass on C first, so C to F, C to F, to F, draw the first arc, change the radius to E, but don't change the center, the parallel one, that's it.

73
00:12:55,379 --> 00:13:32,419
Okay, now you change center to F and repeat. So F, C, till it crosses the previous one over there, and change the radius, not the center, F, D, F, D, you have to be accurate here, and draw the parallel line.

74
00:13:32,419 --> 00:13:47,730
okay so we have twin arches like this okay great for the bigger arches you need a big compass

75
00:13:47,730 --> 00:13:54,750
with a small one you would you wouldn't be able to do this so you are going to cover

76
00:13:54,750 --> 00:14:22,990
from F to A, okay, so from F, sorry, from F to A, and you draw this big arc, okay, so, sorry,

77
00:14:22,990 --> 00:14:35,980
I made a mistake, so I'm going to repeat, F, A, F, A, you draw this arc, with the same radius you

78
00:14:35,980 --> 00:14:54,909
change to a F and do the same a F same radius again like this so you have the

79
00:14:54,909 --> 00:15:19,190
bigger arc and you're going to change the radius to a e a e this compass doesn't

80
00:15:19,190 --> 00:15:58,049
work that well so so a e sorry again a e that's it a e and f b with the same radius f b you draw

81
00:15:58,049 --> 00:16:12,899
the parallel arc. Good. So for these two parallel arches, just for you to have it clear, you

82
00:16:12,899 --> 00:16:20,100
use this center for these two, passing through these two points, and you use F for these

83
00:16:20,100 --> 00:16:26,440
two arches, passing through A and B.

84
00:16:26,440 --> 00:16:32,000
Okay, and for the last part, we are going to place here the circles.

85
00:16:32,860 --> 00:16:43,139
In order to do that, you are going to place the midpoint of this segment, of the segment BC, the midpoint.

86
00:16:43,139 --> 00:16:48,899
If you did it right, here you have 8 centimeters.

87
00:16:49,500 --> 00:16:53,659
So you are going to place the midpoint, that is 4.

88
00:16:53,659 --> 00:17:02,980
okay so but by my advice is that you measure everything up because maybe you have or you

89
00:17:02,980 --> 00:17:10,319
have here a little mistake you could also do the segment by sector that you should do by now

90
00:17:10,319 --> 00:17:18,900
and that you should know by now sorry of the segment bc okay but this is again the midpoint

91
00:17:18,900 --> 00:17:31,460
okay four of eight and that distance with a compass you are going to take the distance

92
00:17:31,460 --> 00:17:39,299
we are going to name this point m for example you don't need to to name the

93
00:17:39,299 --> 00:17:44,660
or to write on the letters okay because you are going to erase it

94
00:17:44,660 --> 00:17:55,779
of them later so don't name it i'm naming them for you to understand so i'm taking

95
00:17:55,779 --> 00:18:04,059
the distance fm and this distance you transport carefully here

96
00:18:04,059 --> 00:18:12,319
so again fm you transport with the compass if you don't have a big compass

97
00:18:12,319 --> 00:18:24,599
you could also use the ruler you can measure this distance that is 13.1 in my case and I'm

98
00:18:24,599 --> 00:18:32,039
transporting up the same distance okay this way you will get here the center

99
00:18:32,039 --> 00:18:44,160
O of the future circles so to know the radius of the circles you want to draw

100
00:18:44,160 --> 00:18:58,720
you are going to connect A with O okay so AO and we are going to draw here a

101
00:18:58,720 --> 00:19:08,819
line that connects A, O and these two points. These two points are going to be

102
00:19:08,819 --> 00:19:27,980
the tangency points. So if you take now the compass you can draw one arc passing

103
00:19:27,980 --> 00:19:50,289
through tangent to the arches first circle okay and second circle that is the

104
00:19:50,289 --> 00:20:00,529
other circle that's it okay center there passing through the two points and that's it
