Across
- 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
Down
- 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.
