Transversal angle pairs

Front

What are transversal angles?

Back

Transversal angles are angles formed when a transversal intersects two or more lines.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines when a transversal crosses them.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are congruent.

Front

What is the relationship between consecutive interior angles when two parallel lines are cut by a transversal?

Back

Consecutive interior angles are supplementary.

Front

If ∠L = 51°, what is the measure of its corresponding angle?

Back

The measure of the corresponding angle is also 51°.

Front

If ∠M = 133°, what is the measure of its alternate interior angle?

Back

The measure of the alternate interior angle is also 133°.
