segment and angle addition postulate

Front

What is the Segment Addition Postulate?

Back

The Segment Addition Postulate states that if point B is between points A and C, then AB + BC = AC.

Front

If AB = 5 and BC = 7, what is AC?

Back

AC = AB + BC = 5 + 7 = 12.

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

If m∠AOB = 30° and m∠BOC = 25°, what is m∠AOC?

Back

m∠AOC = m∠AOB + m∠BOC = 30° + 25° = 55°.

Front

Define a ray in geometry.

Back

A ray is a part of a line that starts at an endpoint and extends infinitely in one direction.

Front

What is the difference between a line segment and a line?

Back

A line segment has two endpoints, while a line extends infinitely in both directions.

Front

If GH = 8 and HI = 17, what is GI?

Back

GI = GH + HI = 8 + 17 = 25.

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

If AC = 22 and AB = 7, what is BC?

Back

BC = AC - AB = 22 - 7 = 15.

Front

What is the sum of the angles in a triangle?

Back

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