What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in similar positions on two parallel lines cut by a transversal. They are equal in measure.

What is the measure of a straight angle?

Back

A straight angle measures 180 degrees.

Front

What is the Angle Addition Postulate?

Back

The Angle Addition Postulate states that if point B is in the interior of angle AOC, then the measure of angle AOB plus the measure of angle BOC equals the measure of angle AOC.

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any quantity is equal to itself, e.g., a = a.

Front

What is the Transitive Property?

Back

The Transitive Property states that if a = b and b = c, then a = c.

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 Linear Pairs?

Back

Linear pairs are two adjacent angles that form a straight line. Their measures add up to 180 degrees.

Front

What is the Substitution Property?

Back

The Substitution Property states that if two values are equal, one can be substituted for the other in any expression.

Front

What is the measure of ∠6 if it is a corresponding angle to ∠2 which measures 154 degrees?

Back

∠6 measures 154 degrees.

Front

How do you find the measure of an angle in a linear pair?

Back

To find the measure of an angle in a linear pair, subtract the measure of the known angle from 180 degrees.
