Segment and Angle Proofs

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 a midpoint in geometry.

Back

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

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 Addition Property of Equality?

Back

The Addition Property of Equality states that if you add the same value to both sides of an equation, the two sides remain equal.

Front

If A is the midpoint of segment HP, what can be said about segments HA and AP?

Back

HA = AP.

Front

What is the relationship between complementary angles?

Back

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

Front

What is the relationship between supplementary angles?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If m∠ABC = 52°, what is the measure of its complement?

Back

The measure of its complement is 38°.

Front

If m∠EFG = 63°, what is the measure of its supplement?

Back

The measure of its supplement is 117°.

Front

What is the formula for finding the measure of an angle formed by two intersecting lines?

Back

The measure of an angle formed by two intersecting lines is equal to the sum of the measures of the opposite angles.
