PLEASE HELP!! Write a paragraph to proof to show that if <1 and <2 are congruent supplementary angles, then <1 and <2 are right angles

Step-by-step explanation:

Supplementary angles are two or more angles whose the addition of their measures add up to .

Given: <1 and <2.

<1 + <2 =   (supplementary angles)

If <1 ≅ <2 (congruent property), then we have;

<1 + <1 =  

2<1 =  

<1 =

   =

<1 =

So that since <1 and <2 are congruent, then;

<1 ≅ <2 ≅

Therefore if <1 and <2 are supplementary and congruent, then they are right angles.
