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

What is the Angle Addition Postulate?

Back

The Angle Addition Postulate states that if point B is in the interior of angle AOC, then the measure of angle AOB plus the measure of angle BOC equals the measure of angle AOC.

Front

Define 'midpoint' in the context of a line segment.

Back

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

Front

If B is the midpoint of segment AC, what is the relationship between AB and BC?

Back

AB = BC.

Front

How do you find the length of a segment if you know the coordinates of its endpoints?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the formula for finding the midpoint of a segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint M = ((x1 + x2)/2, (y1 + y2)/2).

Front

If AB = 8 and B is the midpoint, what is the length of segment AC?

Back

AC = 2 * AB = 16.

Front

What is the relationship between angles formed by two intersecting lines?

Back

The angles are vertical angles and are equal to each other.

Front

If two angles are complementary, what is the sum of their measures?

Back

The sum of their measures is 90 degrees.

Front

What is the definition of a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.
