Okay, so we're focusing on alternate interior angles, and we're looking to focus on angle f, c, and j.
00:19
Okay, so let's get our picture.
00:21
And so we've got a line segment a, g, right? and we have a line segment e, b, that intersects at c.
00:35
And we have another line segment here.
00:38
That is d, h, which intersects at both j and f.
00:43
Okay, so we're focusing in on angle f, c, j, which is this angle right here.
00:51
And because we're working at alternate interior angles, i have to focus on two lines cut by a transversal.
00:57
So if i use this green line as my transversal here, and these two lines as the lines being cut, i need an angle that's on the opposite side of the transversal, but in between the two lines...
