Flashcard 2-2: Angles and Transversal Lines

Front

What is the relationship between angle y and angle x when they are alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What is the relationship between angle y and angle x when they are alternate exterior angles?

Back

Alternate exterior angles are angles that lie outside two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie between two parallel lines on the same side of the transversal. They are supplementary, meaning their measures add up to 180°.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

The alternate interior angles are equal.

Front

If two parallel lines are cut by a transversal, what can be said about the consecutive interior angles?

Back

The consecutive interior angles are supplementary.

Front

If angle x is 7° and angle y is an alternate interior angle, what is the measure of angle y?

Back

Angle y is also 7°.

Front

If angle x is 5° and angle y is an alternate exterior angle, what is the measure of angle y?

Back

Angle y is also 5°.

Front

What is the measure of a missing angle if one angle is 95° and they are consecutive interior angles?

Back

The missing angle is 85°.

Front

If angle x is 12° and angle y is a corresponding angle, what is the measure of angle y?

Back

Angle y is also 12°.
