B. B, Q, T
C. A, B, T
D. T, A, Q

2. What is another name for AB?

B. AT
C. BQ
D. QB

3. Name a line in plane Z.
A. AT
B. AW
C. AQ
D. BQ

4. Name the intersection of planes Z and W.
A. BZ
B. AW
C. AB
D. BQ

5. How many lines are in plane Z?
B. 4
C. 6

6. Which of the following statements is always false?
A. The intersection of a line and a plane is a point.
B. There is only one plane perpendicular to a given plane.
C. Collinear points are also coplanar.
D. A plane contains an infinite number of points.

7. Section 1.2 Linear Measure!
L.T.#1: Be able to use the Segment Addition Postulates to find the lengths of segments and the values of variables!
Line Segment: A line that has 2 endpoints and can be measured
Find the length of segment AB. A B

8. Congruent Segments: segments with the same __________ ; length
Is AB BC? If so, why?
Yes because they have the same length. A B C 3 8 13
Notation is important!
AB BC is read “segment AB is congruent to segment BC.”
AB = BC is read “the length of segment AB is equal to the length of segment BC.”

9. Adding and Subtracting Segments:
Betweenness of Points: You can find the length of a segment by adding together two smaller segments. A B C
Find the length of AC. A B C 13 6
Find DE and EF. Does this check? (add up to 50?)
Find the length of AB if
AC = 22 A B C 10

10. Adding Segments If DF = 50, find the value of x.
Solve for c and YZ if Y is between X and Z.
XY= 11, YZ = 4c, and XZ = 83 D E F
2x - 8
3x - 2
