point

9. Vocabulary: A flat surface that continues infinitely in all directions
plane

10. What formula is this and what is it used for?
This is the Midpoint formula and is used to find the point that divides a line segment into two congruent segments.

11. Fill in the blank. Two planes intersect at a ___________.
line

12. Vocabulary: An exact location in space with an indefinite shape and size
point

13. Name the intersection of WT and TR.X B W R Y C A
Point T

14. How many points does it take to make a line?
at least 2

15. Where do AB and CR intersect?X B W R Y C A
They don’t intersect

16. Vocabulary: An object with no thickness that continues infinitely in two directions
line

17. Where do plane WCA and plane BXY intersect?BA

18. If VR = 6x + 3 and x = 2 now, 6(2) + 3 VR = 15
If Point R is between points V and W, and you are given that VR = 6x + 3, RW = 4x + 5, and VW = 28, what is the value of x and what is the length of VR?
6x x + 5= 28 10x + 8 = 28 10x = 20 so… x = 2
If VR = 6x + 3 and x = 2 now, 6(2) + 3 VR = 15

19. Vocabulary: An object with one endpoint that continues infinitely in one direction
ray

20. What formula is this and what is it used for?
This is the Distance formula and is used to find the length of a line segment.

21. Vocabulary: Points that do not lie on the same line
non-collinear

22. Where do plane J and plane K intersect?F G D J C A B E EG

23. Which illustration below shows a correctly bisected segment?
B is correct

24. Vocabulary: Points that lie on the same line
collinear

25. What is the midpoint of HI on the number line below?
H I J K
-3.5

26. Name all lines that intersect at point AX B W R Y C A
CA, AC, AY, YA, BA, AB

27. What is the midpoint of (3, -5) and (-7, 8)?

28. Vocabulary: Points that do not lie on the same plane
non-coplanar

29. Find the length of AB. 5 2x 3x + 2 A X B Y 37
AX + XB + BY = x + 3x + 2 = 37 x = 6 So…. AB = 5 + 2x = 5 + 2(6) = 17

30. What is the measure of RS?V R S

31. Vocabulary: A point, line, ray, line, line segment or plane that intersects the segment at the midpoint.
bisector

32. Name three planes that intersect at point R.X B W R Y C A
Sample answer: TRC, CRY, TRY

33. What is the measurement of IK on the number line below?
H I J K 6

34. If Point M is the midpoint of JK, JM = 3x + 2 and MK = x – 6, then what is the value of x?
3x + 2 = x – 6 2x + 2 = -6 2x = -8 so… x = -4
