Answer:
Given: An Angle in the figure is right angle. Its measure = 90°
So,
∠2 = 90° ( vertically opposite angles are equal )
∠1 + ∠2 = 180° ( Linear Pair )
∠1 = 180 - 90
∠1 = 90°
So, ∠1 and ∠2 are
Right angles because measure of both angles are 90°.
Adjacent angles because both a common arm and a common vertex.
Supplementary angles because sum of both angles is 180°.
