Which relationship describes angles 1 and 2?

select each correct answer.

vertical angles

complementary angles

adjacent angles

supplementary angles

∠1 and ∠2 are complementary and Adjacent angles .

Step-by-step explanation:

Definition of complementary angles

Two Angles are said to be Complementary when they add up to 90 degrees .

As given

∠1 + ∠2 + 90° = 180°

(By using the linear pair property)

∠1 + ∠2 = 180° - 90°

∠1 + ∠2 = 90°

Definition of Adjacent angles

Two angles are Adjacent when they shares  common side and a common vertex .

As shown in the figure

∠1 and ∠2 shares the common side and a common vertex .

Therefore ∠1 and ∠2 are complementary and Adjacent angles .
