Answer: Complementary
Explanation:
When the measures of two angles are added upto 90°, then we say the pair of angles are complementary angles.
Given : Angles 1 and 2 from a right angle .
It means angle 1 and angle 2 added upto 90°. [ ∵ Measure of right angle is 90°].
Then, by definition of complementary angles, the word describes the measures of Angles 1 and 2 is "Complementary".
