segments and angles addition

Front

What is the Segment Addition Postulate?

Back

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

Front

What is the Angle Addition Postulate?

Back

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

Front

If AB = 5 units and BC = 3 units, what is AC?

Back

AC = AB + BC = 5 + 3 = 8 units.

Front

If angle A measures 30 degrees and angle B measures 50 degrees, what is the measure of angle C if angle A + angle B + angle C = 180 degrees?

Back

Angle C = 180 - (30 + 50) = 100 degrees.

Front

What is the definition of a segment?

Back

A segment is a part of a line that has two endpoints.

Front

What is the definition of an angle?

Back

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

Front

If CD = 12 units and DE = 4 units, what is CE?

Back

CE = CD + DE = 12 + 4 = 16 units.

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 angle X measures 70 degrees, what is the measure of its complement?

Back

The complement of angle X = 90 - 70 = 20 degrees.
