Question

If an angle is congruent to its supplement then it is a right angle? True or false?

Answer 1

Answer:

true

Step-by-step explanation:

Supplementary angles are any two angles whose measures sum to 180 degrees. Supplementary angle pairs will either be two right angles (both 90 degrees) or be one acute angle and one obtuse angle. If two angles are both supplementary to the same angle, then the two angles are of equal measure  two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
