Segment and Angle Proofs Practice

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 m∠AOB + m∠BOC = m∠AOC.

Front

Define the Addition Property in geometry.

Back

The Addition Property states that if equal quantities are added to equal quantities, the sums are equal.

Front

What does it mean for angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the definition of an angle bisector?

Back

An angle bisector is a ray that divides an angle into two congruent angles.

Front

State the Vertical Angles Theorem.

Back

The Vertical Angles Theorem states that if two angles are vertical angles, then they are congruent.

Front

What is a linear pair of angles?

Back

A linear pair of angles is a pair of adjacent angles formed when two lines intersect, and they are supplementary.

Front

Explain the Substitution Property.

Back

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

Front

What is the Transitive Property of equality?

Back

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

Front

How do you express the sum of angles in a triangle?

Back

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

Front

What is the relationship between complementary angles?

Back

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