Question

In the diagram above, ∠1=135° . Find the measure of ∠2.

Answer 1

Angle 2 = 45 degrees

Explanation:

Angle 1 = Angle D because they are alternate interior angles.

Angle 3 = Angle A because they are alternate exterior angles.

Angle 1 = 135 degrees

Therefore, Angle D = 135 degrees

180 - Angle D = Angle 2

Angle 2 = 180 - 135

Angle 2 = 45 degrees
