Question

If two angles are supplementary and congruent the measure of each angle is 90 degrees true or false ?

Answer 1

True because a straight line has 180 deg and the half of that is 90 deg

Answer 2

Two angles are supplementary:
means their measures add up to 180°


congruent: their measures are the same

What are the measures of two angles that are congruent and add up to 180?

90 degrees for each


So it is true
