Transversal Angles and Vocab

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are corresponding angles?

Back

Corresponding angles are angles that lie on the same side of the transversal and in corresponding positions relative to the two lines.

Front

What are consecutive interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line, and their measures add up to 180 degrees.

Front

What is the relationship between vertical angles?

Back

Vertical angles are always equal to each other.

Front

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

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

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

Back

Consecutive interior angles are supplementary, meaning they add up to 180 degrees.

Front

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

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.
