Angle Relationships

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 congruent.

Front

What is the equation to solve for x when given angle relationships?

Back

The equation is derived from the relationships between angles, such as supplementary or complementary angles.

Front

What is the measure of angle 1 if it is given that angle 1 and angle 2 are complementary and angle 2 measures 46°?

Back

Angle 1 measures 44°.

Front

Which angles are congruent?

Back

Angles are congruent if they have the same measure.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180°.

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 congruent.

Front

What is the relationship between vertical angles?

Back

Vertical angles are opposite angles formed by two intersecting lines and are always congruent.

Front

What is a transversal?

Back

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

Front

If two angles are supplementary, what is their sum?

Back

The sum of two supplementary angles is 180°.

Front

What is the definition of complementary angles?

Back

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