Parallel Lines Cut by a Transversal

Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is a transversal?

Back

A line that intersects two or more lines at different points.

Front

Define alternate exterior angles.

Back

Angles that are on opposite sides of the transversal and outside the two lines.

Front

Define alternate interior angles.

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What are corresponding angles?

Back

Angles that are in the same position on two different lines cut by a transversal.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the two lines.

Front

If angle 2 is 52 degrees, what is the measure of angle 7 if they are alternate interior angles?

Back

Angle 7 is also 52 degrees.

Front

If angle 4 is 127 degrees, what is the measure of angle 8 if they are corresponding angles?

Back

Angle 8 is also 127 degrees.

Front

What is the relationship between angle 3 and angle 5 if they are consecutive interior angles?

Back

They are supplementary, meaning their measures add up to 180 degrees.

Front

If angle 1 is 70 degrees, what is the measure of angle 8 if they are corresponding angles?

Back

Angle 8 is also 70 degrees.
