Question

what is the measurement of the angle shown below? 30° 180° 60° 120°

Explanation:

Step1: Read the protractor

When using a protractor, we need to check the scale. The outer scale is used here.

Step2: Determine the angle measurement

Starting from the right - hand side (where the protractor's baseline aligns with the ray), we count the degrees. The ray points to 120° on the outer scale of the protractor.

120°
