Segment and Angle Proofs Practice

Front

What is the Segment Addition Postulate?

Back

If point B is between points A and C, then AB + BC = AC.

Front

What does the Vertical Angles Theorem state?

Back

Vertical angles are congruent; if two angles are vertical angles, then they have equal measures.

Front

What is the definition of a segment bisector?

Back

A segment bisector is a point, ray, line, or plane that intersects a segment at its midpoint.

Front

What can be concluded if AB is the bisector of segment PQ?

Back

PF = QF, meaning the two segments are equal in length.

Front

What is the definition of adjacent angles?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

What is the Angle Addition Postulate?

Back

If point B is in the interior of angle AOC, then m∠AOB + m∠BOC = m∠AOC.

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 definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the Substitution Property in geometry?

Back

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

Front

What is the Transitive Property?

Back

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