Segment and Angle Addition

Front

What is Segment Addition Postulate?

Back

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

Front

What is Angle Addition Postulate?

Back

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

Front

Define Linear Pair of Angles.

Back

Two angles that are adjacent and their non-common sides form a straight line.

Front

What are Supplementary Angles?

Back

Two angles whose measures add up to 180 degrees.

Front

What are Adjacent Angles?

Back

Two angles that share a common vertex and a common side but do not overlap.

Front

What is an Obtuse Angle?

Back

An angle that measures more than 90 degrees but less than 180 degrees.

Front

What is an Acute Angle?

Back

An angle that measures less than 90 degrees.

Front

What is a Right Angle?

Back

An angle that measures exactly 90 degrees.

Front

If RT = 36, find x if RT = 2x + 4.

Back

x = 16.

Front

If m∠1 + m∠2 = 180°, what can we say about ∠1 and ∠2?

Back

They are supplementary angles.
