Okay, so now we are going to draw a straight line tangent to the circumference, but instead of having a point, okay, we have a direction, okay? 00:00:00
We want to draw a tangent line here, okay, following this direction, or also here, okay? We're going to draw it also there. 00:00:10
So, the first thing we are going to do is a perpendicular line to this direction, okay, that pass through the center, okay? 00:00:18
So I put the square set here, the hypotenuse of the square in the direction line. 00:00:27
And now I put the cartabon, I turn the square, and all the lines that I can draw here are going to be perpendicular to the direction. 00:00:40
but I do it passing through the center okay yeah those two lines are 00:00:54
perpendicular one to each other okay so now what I have here is the point of 00:01:02
tangent okay the line that I want to draw must pass through this this point 00:01:08
and or or also it can pass through this other point okay this is possible too 00:01:14
Okay, well, so now the line must be parallel to this direction and perpendicular to the line that we have drawn. 00:01:21
Okay, so I'm going to put again the square in the direction, down below the cartabon, 00:01:31
and instead of turning the square, I'm going to slide it, just slide it. 00:01:38
Okay, and this is the solution, okay, this is the line tangent to the circumference. 00:01:44
Okay, and parallel to this direction. 00:01:51
But here, okay, we have another possible solution, okay? 00:01:54
Just keep in mind, oops, sorry. 00:02:04
Keep in mind that there are two solutions, okay? 00:02:10
This is perpendicular to, and this is perpendicular to, okay? 00:02:21
Once again, what's the beauty of tangents? 00:02:25
That we can link, okay? 00:02:28
Imagine the line, we can link the line with the circumference, with the arch. 00:02:34
