Question

what is the measurement of the angle shown below? 100° 180° 10° 80°

Explanation:

Step1: Read the protractor

When using a protractor, we align the center of the protractor with the vertex of the angle and one side of the angle with the baseline of the protractor.

Step2: Determine the measurement

Looking at the outer scale (since the angle is measured from the left - hand side baseline), we can see that the other side of the angle points to 100. So the angle measurement is 100°.

Answer:

100°
