Parallel Lines Cut by a Transversal - Vocabulary

Front

What are Alternate Interior Angles?

Back

Angles that are located on opposite sides of the transversal and inside the two parallel lines. They are congruent.

Front

Define a Transversal in geometry.

Back

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

Front

What are Parallel Lines?

Back

Two lines that are in the same plane and never intersect, no matter how far they are extended.

Front

What are Same Side Exterior Angles?

Back

Angles that are located outside the parallel lines and on the same side of the transversal. They are supplementary.

Front

Describe Alternate Exterior Angles.

Back

Angles that are located on opposite sides of the transversal and outside the two parallel lines. They are congruent.

Front

What are Corresponding Angles?

Back

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

Front

What is the relationship between Same Side Interior Angles?

Back

They are located on the same side of the transversal and inside the parallel lines. They are supplementary.

Front

How do you identify Alternate Interior Angles in a diagram?

Back

Look for angles that are on opposite sides of the transversal and between the two parallel lines.

Front

What is the significance of the Transversal in geometry?

Back

It helps to establish relationships between angles formed when it intersects parallel lines.

Front

What are the properties of Parallel Lines?

Back

They have the same slope and will never meet, regardless of how far they are extended.
