1. Which pair of angles are on opposite sides of the transversal and between the parallel lines?

a

Corresponding angles

b

Alternate interior angles

c

Alternate exterior angles

d

Consecutive interior angles

2. If two parallel lines are cut by a transversal, and one corresponding angle measures 75°, what is the measure of its corresponding angle?

a

15°

b

75°

c

105°

d

180°

3. When a transversal intersects two parallel lines,   angles are congruent.

4. Consecutive interior angles are   when parallel lines are cut by a transversal.

5. In the diagram below, lines 'a' and 'b' are parallel, and line 't' is a transversal. If angle 1 measures 110°, what is the measure of angle 5? Explain your reasoning.

6. Alternate exterior angles are always supplementary when formed by a transversal intersecting parallel lines.

T

True

F

False

7. Vertical angles are always congruent.

T

Match each angle relationship with its definition.

8. Corresponding Angles

 

a. Angles on the same side of the transversal and between the parallel lines.

9. Alternate Interior Angles

 

b. Angles in the same relative position at each intersection.

10. Consecutive Interior Angles

 

c. Angles on opposite sides of the transversal and between the parallel lines.
