2.5 & 2.6 Mini Quiz Practice

Given: B is the midpoint of AC.

Conclusion: AB + BC = AC

Justification: __________________________

• segment addition postulate

• definition of midpoint

• definition of bisector

• definition of straight angle

• given

Given: QR $\perp$ QP. 
What should you conclude by definition of perpendicular?

• <RQP is a right angle

• QR + RP = QP

• <RQP is complementary

• m<RQP = 180

• m<RQP = 90

Given: The figure with angles 1, 2, 3, & 4. What should you conclude by the vertical angles theorem?

• m<1 = m<3

• <1 and <3 are right angles

• <3 and <4 are a linear pair

•  $<1\cong<3$  

• <2 and <3 are vertical angles

Given: <1 and <2 are complementary.

What can you conclude?

• m<1 + m<2 = 180

• m<1 + m<2 = 90

• m<1 = m<2

• nothing

Given: <1 and <2 are a linear pair.

Conclusion: m<1 + m<2 = 180.

Justification: ______________________________

• angle addition postulate

• definition of straight angle

• definition of linear pair

• definition of complementary

• definition of supplementary

Which of the following is an example of the transitive property?

• If x = 5 and and 5 = y, then x = y.

• If x = y then y = x

• x = x

• If 2x + 4 = 2, then x = -1

• If x = 5 and x = y, then y = 5.

Which of the following conclusions CANNOT be made just by looking at the diagram?

• GH and AB intersect at D

• <GDA and <HDB are vertical angles

• D is the midpoint of GH

• G, D, and H are collinear

Given: PL is the angle bisector of <RPQ

What can you conclude by definition of angle bisector?

• m<RPL = m<LPQ

• <RPL + m<LPQ = m<RPQ

• <RPQ is acute

• m<RPQ = 90
