vertical
complementary
supplementary

Answer 1

Answer :- ∠1 and ∠2 are right angles, vertical and supplementary angles.

Explanation:-

From the given diagram we can see there is intersection of two lines and form right angle.

⇒The lines are perpendicular lines and∠1 and ∠2 both are vertically opposite angles [ pair of opposite angles made by two intersecting lines].

⇒∠1 and ∠2 are also a right angle.

⇒ ∠1=∠2=90°

⇒∠1+∠2 =180° [sum of two right angles is 180°]

⇒∠1 and ∠2 supplementary angles.

Answer 2

∠1 and ∠2 are RIGHT ANGLES, VERTICAL ANGLES, and SUPPLEMENTARY ANGLES. 

Hope this helps!
