Segment and Angle Proofs

Front

What is the Congruent Complements Theorem?

Back

If two angles are complements of the same angle (or congruent angles), then the two angles are congruent.

Front

What is the Substitution Property?

Back

If two quantities are equal, one can be substituted for the other in any expression.

Front

What defines perpendicular lines?

Back

Two lines are perpendicular if they intersect to form right angles.

Front

What is the Addition Property of Equality?

Back

If you add the same value to both sides of an equation, the two sides remain equal.

Front

What is the Subtraction Property of Equality?

Back

If you subtract the same value from both sides of an equation, the two sides remain equal.

Front

What is the Definition of a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What does it mean for angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What is the Transitive Property?

Back

If a = b and b = c, then a = c.

Front

What is the Reflexive Property?

Back

Any quantity is equal to itself (a = a).

Front

What is the Definition of bisect?

Back

To bisect an angle or segment means to divide it into two equal parts.
