Segment Addition & Angle Addition Postulate (1-1)

Front

Using the Segment Addition postulate, which is the correct equation relating the segments? Options: AM + MB = AMB , AB + AM = MB, AM + MB = AB, A + B = AMB

Back

AM + MB = AB

Front

What is the length of PR? Options: 11, 8, 5, 3

Back

11

Front

2x + 20 + 9 = x + 21

Back

Correct equation modeling the lengths shown.

Front

Use Segment Addition Postulate to write and solve for x.

Back

7

Answer explanation

Segment Addition Postulate

AB + BC = BC

2x + 3x + 5 = 40

5x + 5 = 40

5x = 35

x = 7

Front

Use Segment Addition Postulate to write an equation and solve for x.

Back

x = 2

Answer explanation

Segment Addition Postulate

PQ + QR = PR

6 + 2x - 2 = 3x + 2

2x + 4 = 3x + 2

-1x = -2

x = 2

Front

What is the measure of the angle? Options: 50°, 65°, 75°, 70°

Back

65°

Front

What is the measure of the angle? Options: 25°, 45°, 60°, 35°

Back

25°

Front

Find m∠ABC.

Back

105°

Front

Find m∠A.

Back

25°

Front

Back

50°

Answer explanation

Use Angle Addition Postulate

m∠NME + m∠ EML = m∠NML

m∠NME + 88 = 138

m∠NME = 138 - 88

m∠NME = 50
