Transversals and Angle Pairs

Front

What is a transversal line?

Back

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

Front

Identify corresponding angles.

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

Front

What are consecutive interior angles?

Back

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

Front

Define 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 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

If line a is a transversal intersecting lines b and c, what are the corresponding angles?

Back

The angles that occupy the same relative position at each intersection of the transversal with the two lines.

Front

How do you identify consecutive interior angles in a diagram?

Back

Look for angles that are on the same side of the transversal and between the two lines.

Front

What is the relationship between alternate interior angles when the lines are parallel?

Back

Alternate interior angles are equal when the lines are parallel.

Front

What is the sum of consecutive interior angles when the lines are parallel?

Back

The sum of consecutive interior angles is 180 degrees.
