1. Two angles whose sum is 90 degrees are called:
Supplementary angles
Complementary angles
Vertical angles
Adjacent angles
2. When two straight lines intersect, the angles opposite each other are called:
Linear pairs
Complementary angles
Vertical angles
Corresponding angles
3. Two angles that share a common vertex and a common side but no common interior points are called angles.
4. If two angles form a linear pair, then they are angles, meaning their sum is 180 degrees.
5. What is the measure of the angle complementary to an angle measuring 35 degrees?
6. If ∠A and ∠B are supplementary angles and m∠A = 110°, what is m∠B?
7. Use the diagram below to answer the following questions.
a) Name a pair of vertical angles.
b) Name a pair of adjacent angles.
c) Name a linear pair.
8. All adjacent angles are also supplementary angles.
True
False
9. Vertical angles are always congruent.
True
False
