Parallel Lines and Transversals

Front

What are Consecutive Interior Angles?

Back

Consecutive Interior Angles are pairs of angles that are on the same side of the transversal and inside the two lines.

Front

How many pairs of corresponding angles are formed when a transversal intersects two parallel lines?

Back

There are 8 pairs of corresponding angles.

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that are on opposite sides of the transversal and inside the two lines.

Front

What is a transversal?

Back

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

Front

What are Corresponding Angles?

Back

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

Front

What are Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that are on opposite sides of the transversal and outside the two lines.

Front

What are Same-Side Interior Angles?

Back

Same-Side Interior Angles are pairs of angles that are on the same side of the transversal and inside the two lines.

Front

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

Back

Corresponding angles are equal.

Front

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

Back

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

Consecutive interior angles are supplementary (add up to 180 degrees).
