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

Back

AB = BC.

Front

Find AB if B is the midpoint of AC and AC = 16.

Back

AB = 8.

Front

What is the definition of a midpoint?

Back

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

Front

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

Back

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

Front

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

Back

The sum of the measures of two supplementary angles is 180 degrees.

Front

If angle A and angle B are complementary, what is the sum of their measures?

Back

The sum of the measures of two complementary angles is 90 degrees.

Front

What is the Angle Addition Postulate?

Back

The Angle Addition Postulate states that if point D is in the interior of angle ABC, then m∠ABD + m∠DBC = m∠ABC.

Front

If m∠1 = 40° and m∠2 = 50°, what is m∠3 if ∠1 and ∠2 are adjacent and form a straight angle?

Back

m∠3 = 180° - (m∠1 + m∠2) = 180° - 90° = 90°.

Front

What is the relationship between angles formed by intersecting lines?

Back

Vertical angles are equal, and adjacent angles are supplementary.
