If the exterior sides of two adjacent angles are perpendicular, then the angles are _____ angles. complementary right vertical supplementary
Accepted Solution
A:
Adjacent angles are when the 2 angles have a common vertex and a common arm. if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles. Then the sum of the 2 adjacent angles is a right angle - 90°. When 2 angles add up to 90°, they are called a pair of complementary angles.
