Segment and Angle Proofs

Front

What is the definition of a bisector in geometry?

Back

A bisector is a line, ray, or segment that divides an angle or segment into two equal parts.

Front

What does it mean for a point to be the midpoint of a segment?

Back

A midpoint is a point that divides a segment into two equal lengths.

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 definition of complementary angles?

Back

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

Front

What is the Vertical Angle Theorem?

Back

The Vertical Angle Theorem states that vertical angles are congruent, meaning they have the same measure.

Front

What is the definition of a right angle?

Back

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

Front

What is the Transitive Property in geometry?

Back

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

Front

What is the definition of congruent segments?

Back

Congruent segments are segments that have the same length.

Front

What is the definition of an angle?

Back

An angle is formed by two rays with a common endpoint called the vertex.

Front

What is the definition of a segment?

Back

A segment is a part of a line that is bounded by two distinct endpoints.
