Angles and parallel lines

Front

What are corresponding angles?

Back

Corresponding angles are pairs of 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

Alternate interior angles are pairs of angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are exterior angles?

Back

Exterior angles are angles that are formed outside the two parallel lines when they are cut by a transversal.

Front

If angle A and angle B are corresponding angles, what can we say about their measures?

Back

Angle A and angle B are equal in measure.

Front

If angle P measures 60 degrees, what is the measure of angle C if they are supplementary?

Back

Angle C measures 120 degrees.

Front

What is the sum of the measures of angles on a straight line?

Back

The sum of the measures of angles on a straight line is 180 degrees.

Front

How do you find the measure of an angle when given its adjacent angle?

Back

If the adjacent angle is known, subtract its measure from 180 degrees if they are supplementary, or from 90 degrees if they are complementary.

Front

What is the relationship between alternate exterior angles?

Back

Alternate exterior angles are equal in measure when two parallel lines are cut by a transversal.

Front

What is a transversal?

Back

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

Front

If two parallel lines are cut by a transversal, how many pairs of corresponding angles are formed?

Back

Four pairs of corresponding angles are formed.
