Answer:
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.
