1. If two lines are coplanar, __**CAN**__ they intersect?

2. If two lines are coplanar, __**do they have to**__ they intersect?

3. A pair of opposite rays form a line.
 * 1) 3-#7 True or False

4. A pair of opposite rays form a segment.

5. A pair of opposite rays have the same endpoint.

6. Two planes intersect at a point.

7. Two lines intersect at exactly 3 points.

8. How many points do you need to define (name) a line?

9. How many points do you need to define (name) a plane?

A __**BISECTOR**__ cuts something in half. Usually a segment or angle. 10. If a 70 degree angle is **__bisected__**, the resulting smaller angles will each measure degrees.

11. A segment that is 18 inches long is **__bisected__**, how long are the two, new, smaller segments?

12. An angle was __**bisected**__, the new angles are each 34 degrees. How big was the original angle?

13. A, B, and X are collinear points. B is between A and X. if AB =10, and AX=30, how long is BX? (hint: draw a picture)

For #14-16, us this diagram to answer: 14. What is the length of QS?

15. What is the length of RT?

16. What is the __**MIDPOINT**__ (point in the middle) of QT?

For #17-18use this diagram to answer: 17. If the measure of angle MLN is 30 degrees, what is the measure of angle MLP?
 * ray LN bisects angle MLP,** *

18. If the measure of angle PLM is 80 degrees, what is the measure of angle NLP?

For #19-21 use this diagram to answer:

19. Name one pair of vertical angles

20. Name a pair of **STRAIGHT ANGLES**.

21. Which two angles are adjacent to angle 4?
