Proving the Congruent Supplements Theorem

Answer 1

If two angles are each supplementary to a third angle, then they're congruent to each other. This is the three-angle version, Supplements of congruent angles are congruent. If ∠A + ∠T = 180° ∠C + ∠T = 180° then the angles are congruent.

I hope this helps you.
