2. a property of space; extension in a given direction:
4. lines that meet at a 90
10. two non collinear rays with a common endpoint
12. a flat figure with no thickness that extends indefinitely in all directions
14. two endpoints and all the points in between them
16. points that lie on the same plane
17. two angles with a common side but no common interior points
19. an angle whose measure is greater than 90 and less than 180
20. angle formed by opposite rays

1. four parts of a coordinate plane
3. point where the x-axis and y-axis meet in a coordinate grid
5. A precise location or place on a plane. Usually represented by a dot.
6. Two non adjacent angles formed by two intersecting line
7. points on the same line
8. geometric elements of equal measure
9. the sum of two angle whos measure is 180
11. the set of all points collinear to two-point
13. point in common of two rays that form an angle
15. the middle point of the line segment
16. the sum of two angle use measure is 90
18. angle whose measure is less than 90
21. is a line with a single endpoint (or point of origin) that extends infinitely in one direction.
