Geometry Unit 1

3. angle An angle that measures more than 90 degrees but less than 180 degrees
6. angles two angles that add up to 90 degrees
7. A figure formed by two rays with a common endpoint
8. points that lie on the same line
9. angle an angle that measures 90 degrees -- perpendicular
10. a statement that is believed to be true but not yet proven
11. a statement that is accepted as true without requiring proof
14. Statement ~q -> ~p, It is formed by reversing AND negating the hypothesis and the conclusion of the conditional to become "if not q, then not p".
15. segment part of a line with two endpoints
18. points that lie on the same plane
20. Having the same measure
21. Statement ~p -> ~q, A conditional statement that negates the hypothesis and conclusion. If not p then not q.
24. points that do not lie on the same plane
25. distance the length of a specific part of a line
26. a straight path that has no thickness and extends in both directions infinitely -- undefined term
27. a statement that can be proven
28. rays two rays that share the same endpoint and form a line
30. angle an angle that measures exactly 180 degrees

1. an example that proves that a conjecture or statement is false
2. statement p -> q, a statement that can be written in if-then form
4. statement p <-> q, A statement that contains the phrase "if and only if"
5. A point that divides a segment into two segments of equal length.
12. angles two angles that add up to 180 degrees
13. points that do not lie on the same line
16. A part of a line, with one endpoint, that continues infinitely in one direction
17. a point at an end of a segment or the starting point of a ray
19. angle an angle that measures less than 90 degrees
22. Statement q -> p, the statement formed by exchanging the hypothesis and conclusion of a conditional statement
23. a flat surface that has no thickness and extends forever -- undefined term
29. A location in space that is represented by a dot and has no dimension -- undefined term
