Read each question carefully and answer to the best of your ability. Use diagrams to help you visualize the angles.

1. What is the measure of an angle that is complementary to an angle measuring 35°?

145°

55°

90°

180°

2. Two angles are supplementary. If one angle measures 110°, what is the measure of the other angle?

70°

20°

90°

180°

3. Angles that add up to 90° are called angles.

4. Angles that are opposite each other when two lines intersect are called angles.

5. Angles that share a common vertex and a common side but do not overlap are called angles.

6. Draw two intersecting lines and label a pair of vertical angles ∠1 and ∠2. Explain why they are vertical angles.

7. Angle A and Angle B are adjacent angles. If Angle A measures 60° and Angle B measures 30°, what type of angle relationship do they also have?

8. Complementary angles always form a straight line.

True

False

9. Vertical angles are always congruent (have the same measure).

True

False
