1. What is the measure of an angle that is complementary to an angle measuring 35°?
45°
55°
145°
180°
2. Two angles are supplementary. If one angle measures 110°, what is the measure of the other angle?
70°
90°
180°
270°
3. Angles that add up to 90° are called angles.
4. Angles that add up to 180° are called angles.
5. When two lines intersect, the angles opposite each other are called angles and they are always .
6. In the diagram below, if angle A measures 60°, what are the measures of angles B, C, and D? Explain your reasoning.
Angle B:
Angle C:
Angle D:
7. Adjacent angles always add up to 90°.
True
False
8. Vertical angles are congruent.
True
False
9. An angle measures (2x + 10)°. Its complementary angle measures (3x - 5)°. Find the value of x and the measure of each angle.
10. Two angles form a linear pair. If one angle is four times the measure of the other, find the measure of both angles.
