Okay, so we are going to use the concept of tangents to link these two lines, okay?
00:00:00
This is one line and this is the other, straight lines, with a circumference, okay?
00:00:07
So imagine that you are a car and you are drawing this way, but in order to turn to the right, you have to stop and then turn, okay?
00:00:11
Because you can't take this corner in a fluent way, okay?
00:00:23
You can do it in a fast velocity, okay?
00:00:27
So what we are going to do is to link it with a circumference, okay?
00:00:31
Maybe you will understand it later.
00:00:36
So the first thing we are going to do is to draw the bisector line of the angle, okay?
00:00:39
Of this angle.
00:00:44
Do you remember how to draw a bisector line?
00:00:45
If you don't remember, I will remind you.
00:00:47
So place the needle of the compass in the vertex of the angle, okay?
00:00:51
just in the corner oops uh here okay taking care and make an arch that cuts the angle okay both
00:00:57
sides of the angle like this yeah this distance and this distance is the same and now placing the
00:01:06
compass in this point let's make another arch okay like this and very very important not closing or
00:01:14
opening the compass just with the same radius we are going to make an arch here
00:01:23
okay like this yeah these two radius must cut each other so now I join the
00:01:28
vertex with this point okay and this is the bisector line okay the bisector line
00:01:37
of this angle okay so once we have the bisector line of the angle we decide how
00:01:46
big or how small we want the circumference what we have to do is to place the center of the
00:01:52
circumference in this line okay this is the most important thing if you don't place the needle of
00:01:59
the compass in the line uh it won't touch it won't link the the straight lines okay so for example
00:02:04
i'm going to place it here okay this is going to be the center of my circumference i'm going to
00:02:12
Call it O, this point O.
00:02:18
And now, from this point, I have to draw perpendicular lines to the given one, okay?
00:02:21
To this line and to this other line.
00:02:28
Do you remember how to do it?
00:02:30
Okay, it's quite easy.
00:02:32
You put here the square set, yeah?
00:02:34
Okay?
00:02:40
Down, the square, sorry, not the square set, the square.
00:02:41
Down below, you put the cartamon and now turn the square, okay?
00:02:43
and put the hypotenuse in the center, okay?
00:02:48
This is the radius of the circumference that I'm going to draw,
00:02:56
and this is the point of tangent, okay?
00:02:59
Here I'm going to draw the link, okay?
00:03:02
This is going to be the first point.
00:03:05
And now I'm going to do the same with the other line, okay?
00:03:08
Turn the square, slide it to the center, okay?
00:03:14
Okay, here I have 90 degrees, and this is my second point, okay, 90 degrees 2.
00:03:18
So now I can draw my circumference with the center in O, okay, and placing the compass from 1 to 2, okay.
00:03:25
This is my circumference, okay.
00:03:37
but the shape that I really wanted sorry that I really wanted to draw is the link itself okay so
00:03:40
I'm going to mark only this part do it with a pencil please not with a pen okay this is just
00:03:53
for you to see okay and I'm going to mark also this part okay and also this part yeah and again
00:04:00
just to mark the solution okay so this is the the link of two lines with a
00:04:22
circumference okay you can do it with a bigger one with a bigger one
00:04:30
circumference with a smaller one okay so the link will be that will be a smaller one
00:04:35
