Solve for x.

• 3

• 6

• 8

• 9

Which is the correct proportion for solving for x?

• no solution
  

Name the dashed segment:

• altitude

• angle bisector

• perpendicular bisector

• median

Find the missing length.

• 10

• 21

• 35

• 9

What is the missing statement in the proof?

• 2m∠ABD=m∠ABD+m∠ABD

• m∠ABD=m∠DBC

• m∠ABC=m∠ABC

• m∠ABD+m∠ABD=m∠ABD+m∠DBC

What is the missing statement in the proof?

• 2m∠ABD = m∠ABD + m∠ABD

• m∠ABD = m∠DBC

• m∠ABC = m∠ABC

• m∠ABD +m∠ABD = m∠ABD + m∠DBC

Find m< JKM

• 90

• 76

• 38

• 83

Determine the Conclusion.

• Then ∠BCA ≅ ∠DCA.

• Then ∠BAC ≅ ∠DAC.

• Then Segment AB is congruent to Segment AD.

• Then ∠BAC and ∠DAC are right angles.

Angle JHG measures 161.

• m∠GHK=80.5,

  m∠KHJ=161

• m∠GHK=161,

  m∠KHJ=80.5

• m∠GHK=80.5,

  m∠KHJ=80.5

• m∠GHK=161,

  m∠KHJ=161

If AD bisects <EDI, then

• <ADE=<IDA

• IA=AE

• ID=ED
