Parallel Cut by Transversal

Front

What is a transversal in geometry?

Back

A transversal is a line that intersects two or more other lines at distinct points.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal.

Front

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

Back

The corresponding angles are equal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between the two lines and on opposite sides of the transversal.

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

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie on the same side of the transversal and between the two lines.

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, meaning they add up to 180 degrees.

Front

If angle 4 is 50 degrees, what is the measure of angle 8 if they are corresponding angles?

Back

Angle 8 is also 50 degrees.

Front

If angle 1 is 135 degrees, what is the measure of angle 3 if they are corresponding angles?

Back

Angle 3 is also 135 degrees.

Front

If angle 6 is 25 degrees, what is the measure of angle 7 if they are alternate exterior angles?

Back

Angle 7 is also 25 degrees.
