answer

DC
AB

question

Which are skew lines? Check all that apply.

answer

c and b
e and c
a and c

question

Are the lines in the diagram perpendicular, parallel, skew, or none of these?
l and m:
l and n:
m and n:

answer

none of these
skew
perpendicular

question

Planes Q and R are parallel. Explain how you know lines a and b are skew.

answer

Skew lines are noncoplanar and do not intersect. Line a lies in plane Q and line b lies in plane R, so the lines are not coplanar. No other plane can be drawn through the lines, so they are not parallel. So, a and b are skew.

question

Segment TQ is 26 units long. What is the length of QV?

answer

answer

23 units

question

What is the measure of AC?

answer

26 units

question

Marissa says that lines a and d will eventually intersect. Is she correct? Explain.

answer

no, because they are skew

question

Planes Q and R are parallel. Lines a and b are shown on planes Q and R, respectively.
Which statement is true about lines a and

answer

They are skew lines.

question

Consider the diagram.
Lines a and d are

answer

perpendicular.

question

In the diagram, line a is the perpendicular bisector of KM.
What is the length of KM?

answer

80 units

question

Janelle says that lines l and m are skew lines.
Is Janelle correct?

answer

No, because the lines are in the same plane

question

Consider the diagram.
What is the length of segment AB?

answer

9

question

Kevin says that lines p and m will eventually intersect.
Is Kevin correct?

answer

No, because they are parallel.

question

Consider the diagram.
Which line segment has the same measure as TQ?

answer

TR

question

Planes Q and R are parallel planes. Plane Q contains line a. Plane R contains line b.
If a third plane could be drawn which contains both lines a and b, then

answer

lines a and b must be parallel.

question

In the diagram shown, the distance between points A and C is the same as the distance between points B and G.
Lines AB and CG are

answer

parallel.

question

In the diagram, TQ is 18 units in length.
What is the length of RS?

answer

25 units
