Segment and Angle Addition Postulates

Front

What is the Segment Addition Postulate?

Back

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

Front

Define a line segment.

Back

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

Front

What is an angle?

Back

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

Front

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

Back

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

Front

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

Back

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

Front

What does it mean for two angles to be complementary?

Back

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

Front

If angle A measures 30 degrees, what is the measure of its complement?

Back

The complement of angle A is 60 degrees (90 - 30 = 60).

Front

What is the formula for finding the measure of an angle in a triangle?

Back

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

Front

If angle B measures 50 degrees and angle C measures 70 degrees, what is the measure of angle A?

Back

Angle A = 180 - (50 + 70) = 60 degrees.

Front

What is a ray?

Back

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