We are going to draw the worksheet Lacus, okay?
00:00:04
So exercise number one
00:00:11
We are going to place
00:00:14
The
00:00:25
Points that keep the same distance from A and B in order to do that
00:00:26
with a compass
00:00:33
We will draw
00:00:35
an arc
00:00:37
from B with any radius
00:00:38
So you draw top and bottom with any radius and with the same radius, so no changing the radius here in the compass, we mark top and bottom again.
00:00:42
okay so you have two a couple of arches that cross each other this we are going to name
00:01:01
these dots as one and two okay place the ruler carefully and connect one and two
00:01:13
and draw the segment this way we are going to get the division of the segment in two we are
00:01:32
going to get the midpoint M and the perpendicular this symbol means perpendicular on M on the
00:01:44
segment. This construction is called segment bisector. Exercise number two is draw the
00:01:56
locus of all points at 25 millimeters from point P. So we are going to draw points or
00:02:22
place points that keep that distance 25 from P. We are going to measure this distance
00:02:31
on a straight line in any direction, we measure with accuracy from P25. We are going to, we
00:02:40
erase the rest of the line, so we keep the 25 millimeters. This is the mark for 25. Draw
00:03:07
an arrowhead clean this arrowhead must be neat clean and an isosceles triangle
00:03:22
and on top of the line we are going to write just in the middle r25 now with
00:03:40
compass we can draw the locus, the geometrical locus, of all dots there, all
00:03:54
dots that keep there, that keep, sorry for the mistake here, that keep 25
00:04:08
millimeters from P. This construction is called circumference. Number three, all
00:04:33
points that keep the same distance from lines R and S. Okay, so in order to place
00:04:58
that, we need to draw from the vertex V, this is the vertex of the angle, these are
00:05:06
two intersecting lines, we have two intersecting lines in one angle, so you
00:05:16
place a compass on V and with any radius you draw the arc, you will get two
00:05:23
points one and two and you can change the radius okay the previous one so I'm
00:05:35
going to do or use a bigger one and from one and two look carefully so from one
00:05:50
one arc and with the same radius than than this one from two you have two
00:06:00
intersecting arches. So again, from 1 with any radius, you don't need to use
00:06:11
this one, you can use a different one, 1 and 2. You will get a 0.3 and this 0.3
00:06:17
keep the same distance from R and from S. So, if you connect with the vertex V, you
00:06:29
will get the construction this is it this construction is called angle by
00:06:42
sector just divides the angle into okay number four locus of all points that
00:06:59
keep 40 millimeters from line R okay good and we are going to measure the 40
00:07:15
millimeters in here we are going to place a square or bevel 90 degrees in
00:07:25
any place on R. We draw the perpendicular and measure, we'll measure 40, that's it.
00:07:38
Erase the rest of the segment, the straight line. We are going to need only 40 and we
00:08:04
We need arrowheads like before, like on the radius, but we need two.
00:08:15
On radius we use one, on measurements we need two arrowheads.
00:08:23
The tip of the arrowhead on 40, this is 40, place the number that way, vertically, and
00:08:31
to the left good and once you have the distance with accuracy place the bevel
00:08:43
or the square on the straight line on our the straight line and the other
00:08:56
ruler is going to be the guide so we are going to draw a parallel keep the ruler
00:09:07
still, and move the square to the tip of the arrowhead.
00:09:13
And you will get, draw the parallel, and that's it.
00:09:19
And name the parallel as a straight line S in lower case.
00:09:26
And the construction is called.
