Intro to Geometry

Angle 1 and angle 2 form a right angle.

The measure of angle 1 is 32°.

What is the measure of angle2?

• 58°

• 122°

• 40°

• 90°

Answer explanation

A right angle is 90°. Since angle 1 and angle 2 make up the bisected right angle they must add to 90°; therefore, 90-32=58. Angle 2 is 58°.
