What are Vertical Angles?

Back

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

Front

Define 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

Define Corresponding Angles.

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

What are Supplementary Angles?

Back

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

Front

What are Complementary Angles?

Back

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

Front

If angle 1 is 45 degrees, what is the measure of its corresponding angle?

Back

The measure of the corresponding angle is also 45 degrees.

Front

If angle 6 measures 45 degrees, what is the measure of angle 7 if they are supplementary?

Back

Angle 7 measures 135 degrees.

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are always equal to each other.

Front

If two angles are alternate interior angles and one measures 55 degrees, what is the measure of the other?

Back

The other angle also measures 55 degrees.
