Parallel Lines Cut by a Transversal

Front

What is the definition of a transversal?

Back

A transversal is a line that passes through two or more parallel lines.

Front

Name the corresponding angle to angle 4.

Back

angle 8

Front

What is the angle relationship between angle 4 and angle 8?

Back

Corresponding angles are equal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles on opposite sides of the transversal but inside the parallel lines.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are equal.

Front

If angle 2 is 127°, what is the measure of angle 6?

Back

Angle 6 is also 127° because they are alternate interior angles.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are angles that are in the same position at each intersection where a straight line crosses two others.

Front

If angle 5 is 52°, what is the measure of angle 1?

Back

Angle 1 is also 52° because they are corresponding angles.

Front

What is the sum of the interior angles on the same side of the transversal?

Back

The sum of the interior angles on the same side of the transversal is 180°.

Front

If angle C is 116°, what is the measure of angle D if they are consecutive interior angles?

Back

Angle D is 64° because consecutive interior angles are supplementary.
