This problem wants us to write a two -column proof.
00:03
So we have this triangle here.
00:07
We have a, e, b, f, c, like this.
00:14
Okay, so we're going to write, draw our columns.
00:18
So we have our statements, and we have our reasons.
00:24
Okay, so first is given.
00:26
So we're given that triangle a, b, c is equal angular.
00:32
And that is given...
