Let's draw a square knowing the side. 00:00:00
And this is the side. 00:00:03
This is the point A and this is the point B. 00:00:05
To build a square we need to place 90 degrees here and 90 degrees here 00:00:10
and find a way to draw the same measure in each side. 00:00:19
So the first thing we have to do is to draw the right angles. 00:00:24
I place the square here, I place the square here and the cartabon down below, now if I 00:00:30
slide the square I can draw parallel lines here, but what I want, what I really want 00:00:51
is a perpendicular line, so I turn the square, I turn it 90 degrees, instead of being here, 00:00:58
I turn it, and now all the lines that I drew here are perpendicular to this one, so I'm 00:01:09
I'm going to draw one in A and another one in B, enlarging it just in case I make it. 00:01:18
This is the first step. 00:01:32
Secondly, I'm going to take the measure AB with my compass, and I'm going to put this 00:01:35
measure the same measure in each perpendicular line okay so now I have 00:01:43
three sides that measure the same with 90 degrees on each and without changing 00:01:51
the aperture of my compass okay I'm going to check that the distance between 00:02:00
this point and the other point I have found is the same so the only thing that 00:02:06
I have to do is to join those two points I'm going to do it with a parallel to AB 00:02:15
so I check that they are really parallel okay so this is my square CD AD AB BC 00:02:21
all the sides measure the same and there are four right angles 00:02:45
