Question

Angle 2 is an____angle and is_____to angle 1.

Angle 5 is an____angle and is_____to angle 8.​

Answer 1

Angle 2: Acute, supplementary

Angle 5: Obtuse, congruent

Explanation:

An acute angle is less than 90 degrees. An obtuse angle is more than 90 degrees. A supplementary angle is an angle equal to 180 degrees when added to another angle. (Angle 1 + angle 2 = 180 degrees.) Congruent angles are equal to each other in degrees. (Angle 5 = angle 8.)
