Geometry Unit 1

2. that lie on the same plane
4. -> p, the statement formed by exchanging the hypothesis and conclusion of a conditional statement
10. q, A statement that contains the phrase "if and only if"
11. statement that is believed to be true but not yet proven
12. location in space that is represented by a dot and has no dimension -- undefined term
13. that lie on the same line
15. segment,part of a line with two endpoints
18. -> ~p, It is formed by reversing AND negating the hypothesis and the conclusion of the conditional to become "if not q, then not p".
19. -> ~q, A conditional statement that negates the hypothesis and conclusion. If not p then not q.
20. flat surface that has no thickness and extends forever -- undefined term

1. the same measure
3. -> q, a statement that can be written in if-then form
5. distance,the length of a specific part of a line
6. point at an end of a segment or the starting point of a ray
7. part of a line, with one endpoint, that continues infinitely in one direction
8. example that proves that a conjecture or statement is false
9. statement that is accepted as true without requiring proof
14. statement that can be proven
16. straight path that has no thickness and extends in both directions infinitely -- undefined term
17. point that divides a segment into two segments of equal length.
