Transversals & Angles

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines cut by a transversal. They are equal in measure.

Front

What are vertical angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the relationship between complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

If angle 1 is 70 degrees, what is the measure of its corresponding angle?

Back

The measure of the corresponding angle is also 70 degrees.

Front

If angle 6 and angle 7 are vertical angles, and angle 6 measures 120 degrees, what is the measure of angle 7?

Back

Angle 7 also measures 120 degrees.

Front

Identify the angle pair: Angle 3 and Angle 5 are on the same side of the transversal and inside the parallel lines. What type of angle pair are they?

Back

They are alternate interior angles.

Front

If angle 2 and angle 3 are supplementary and angle 2 measures 45 degrees, what is the measure of angle 3?

Back

Angle 3 measures 135 degrees.
