2. Words in geometry that we can clearly explain using other known words.
4. The place where two lines or shapes meet or cross.
7. A number that shows where a point is on a line or graph.
10. A part of a line that has two endpoints and includes everything between them.
11. A tiny spot that shows a place in space; it has no size.
14. A word in geometry that isn’t clearly defined but everyone agrees on what it means.
15. Points that are all on the same flat surface (like a piece of paper).
16. A flat surface that goes on forever in all directions, like a giant sheet of paper.
17. A rule in geometry that we accept as true without needing to prove it.
18. The point in the exact middle of a line segment.

1. A line, point, or shape that cuts a segment exactly in half.
3. Two rays that start at the same point but go in opposite directions.
5. How far apart two points are on a line.
6. A part of a line that starts at one point and goes forever in one direction.
8. Line segments that are exactly the same length.
9. Points that are all on the same straight line.
12. A straight path that goes on forever in both directions.
13. If three points are on a line, one point is in the middle of the other two.
