So here we want to show the theorem that says when two angles are inscribed in congruent arcs, those angles are congruent.
00:11
So we want to show that this angle and this angle are congruent because we know that these two arcs are congruent.
00:18
Okay, so what we're going to do is first we can say, well, the measure of arc m or not m, the measure of angle f, a .e is equal to half the measure of arc, f .e, and the measure of angle d.
00:45
D.
00:46
B .c.
00:47
Is equal to half the measure of arc dc.
00:55
So that is by the theorem, let's see, the measure, the theorem that says measure of an inscribed angle is half measure the answer.
01:08
Intercepted arc.
01:09
So theorem, i think that's like in here, well, that doesn't matter the number.
01:16
So theorem intercepted arc and angle.
01:25
So that theorem...
