Okay, so here we have a square and we know that square, all of the corners, they are 90 degree angles.
00:14
And we're drawing a diagonal through the square.
00:18
So you can draw a diagonal this way, but i'm going to draw one this way.
00:22
And this diagonal line bisets, the 90 degree angles.
00:26
So this angles become 45 degrees, so half of 90 degree.
00:31
So this is 45 degrees.
00:32
It's the same thing here, 45 degrees.
00:34
And this is 45 degrees.
00:38
So the first question was to draw a diagonal line we did, and what's the measure of each angle formed by a side and the diagonal.
00:49
So a, theta, is 45 degrees.
00:58
The angle that's formed by a side and the diagonal is going to be 30 degrees...
