Across
- 3. a point that is exactly in the middle of the line segment joining two points.
- 4. a plane is a flat, two-dimensional surface that prolongs infinitely far
- 5. set of two line segments that are equal in length
- 6. Defined terms are words that are given a specific definition in a contract.
- 7. a straight one-dimensional figure that does not have a thickness, and it extends endlessly in both directions.
- 9. a line segment is bounded by two distinct points on a line.
- 12. an equation that calculates the halfway point distance between two known coordinate points
- 14. the amount of space between two points
- 15. all the elements that are present in both sets (common elements of A and B).
- 16. points Points or lines are said to be coplanar if they lie in the same plane.
Down
- 1. Algebraic expression that gives the distances between pairs of points in terms of their coordinates
- 2. terms that don't require a formal definition.
- 5. Collinear points are the points that lie on the same straight line or in a single line.
- 8. a point that marks the end of a line segment or a ray Rays a part of a line that has a fixed starting point but no endpoint
- 10. statement that is taken to be true, to serve as a premise or starting point for further reasoning and arguments.
- 11. rays two rays that have the 'same endpoint and extend in opposite directions
- 13. closed figure made up of line segments (not curves) in a two-dimensional plane.
