Question

. When the sum of the measures of two angles is 90, the angles are called *
complementary angle
supplementary angle
adjacent angle
vertically opposite angle​

Answer 1

Answer:

If the sum of the measures of two angles is 90° they are known as complementary angles. Hence,the pairs of complementary angles are ∠B and ∠N, ∠D and ∠F, ∠Y and ∠E. If the sum of the measures of two angles is 180° they are known as supplementary angles.

Supplementary Angles

Answer 2

when the sum of the measures of two angles is 90 the are called supplementary angle
