Segment Addition and Segment Bisectors

B is the midpoint of AC. Which equation will help me solve for the correct value of x?

• 7x - 6 = 12 - 2x

• 7x - 6 + 12 - 2x = x

• 7x - 6 + 12 - 2x

• RM=6, MS=6
• RM=3, MS=3
• RM=3, MS=6
• RM=6, MS=3

• MQ=4, PQ=8
• MQ=4, PQ=4
• MQ=8, PQ=4
• MQ=8, PQ=8

This point divides a line segment into 2 equal parts.

• point

• vertex

• midpoint

• angle

RS is the segment bisector.  If OQ = 8x-51 and

PO =3x-6 , find the value of PQ?

• 9

• 28

• 12

• 42

• x

Given: AC = AB + AB
Prove: AB = BC
Reason 1: Given
What is Step 1?

• AC = AB + AB

• AB = BC

• AB + BC = AC

• AB + AB = AB + BC

What does it mean to bisect a segment or an angle?

• Split it into 3 equal parts.

• Split it into 2 equal parts.

• Split into 4 equal parts.

• Double it.
