1. Two angles are complementary if their sum is:
45 degrees
90 degrees
180 degrees
360 degrees
2. What type of angles are formed when two lines intersect and are opposite to each other?
Corresponding angles
Alternate interior angles
Vertical angles
Supplementary angles
3. Angles that are on the same side of the transversal and in the same relative position are called angles.
4. The sum of angles on a straight line is degrees.
5. In the diagram below, lines 'm' and 'n' are parallel, and line 't' is a transversal. If angle 1 measures 70 degrees, what is the measure of angle 5? Explain your reasoning.
6. Alternate interior angles are always congruent when two parallel lines are cut by a transversal.
True
False
7. Supplementary angles always form a linear pair.
True
False
Match the angle relationship with its definition.
8. Complementary Angles
a. Angles that add up to 180 degrees
9. Supplementary Angles
b. Angles that are opposite each other when two lines intersect
10. Vertical Angles
c. Angles that add up to 90 degrees
