Angle Relationships with Parallel Lines

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

What are Alternate Interior Angles?

Back

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

Front

What are Alternate Exterior Angles?

Back

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

Front

What are Same Side Interior Angles?

Back

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

Front

What is a Transversal?

Back

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

Front

What is the relationship between Corresponding Angles when lines are parallel?

Back

Corresponding Angles are equal.

Front

What is the relationship between Alternate Interior Angles when lines are parallel?

Back

Alternate Interior Angles are equal.

Front

What is the relationship between Alternate Exterior Angles when lines are parallel?

Back

Alternate Exterior Angles are equal.

Front

What is the relationship between Same Side Interior Angles when lines are parallel?

Back

Same Side Interior Angles are supplementary (add up to 180 degrees).

Front

If two parallel lines are cut by a transversal, what can be said about the Linear Pair of angles formed?

Back

Linear Pair angles are supplementary.
