Complementary and Supplementary Angles

Special names are given to pairs of angles whose sums equal either 90 or 180 degrees. A pair of angles whose sum is 90 degrees are called complementary angles. Likewise, if two angles sum to 180 degrees, they are called supplementary angles.

Answer 2

Step-by-step explanation:

(a) we know that the measure of an acute angle is less than 90degrees. so, 45degrees, 50degrees,55degrees,60degrees,65degrees all are acute angle.

(b) We know that the measure of an obtuse angle is more than 90degrees. so, 120degrees, 125degrees,135degrees,140degrees all are obtuse angle.
