Angles formed by Parallel Lines cut by Transversal Practice

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What is a linear pair of angles?

Back

A pair of adjacent angles that are formed when two lines intersect. The sum of their measures is 180 degrees.

Front

What does it mean for lines to be perpendicular?

Back

Two lines that intersect at a right angle (90 degrees).

Front

Back

The sum of the measures of Angle 1 and Angle 2 is 180 degrees.

Front

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

Back

They are equal in measure.

Front

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

Back

They are equal in measure.

Front

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

Back

They are equal in measure.
