Session 6

Protractor Practice page 1 of 2When you measure an angle you usually have to choose between two numbers because protractors are designed to measure angles that start on either the right or left side. There are two angles to measure in each of the problems on this sheet and the next. The angle on the left side is angle A. The angle on the right side is angle B. Find and record the measure of both angles in each problem.

1 The measure of angle A is ______ degrees.

The measure of angle B is ______ degrees.
