Across 2. to divide into two congruent parts 5. figures that lie in the same plane 7. an angle whose measure is between 0 and 90 degrees 10. A pair of angles with a common vertex whose sides are opposite rays 12. an angle whose measure is between 90 and 180 degrees 13. An angle with 90 degrees 14. You must always draw these to correspond with your work 16. A statement in the form of if and only if 17. three non collinear points define one plane. 22. the length of segment AB 24. an angle whose measure is 180 degrees 25. three undefined terms in geometry 27. a part of a line with one endpoint and extending in one direction 28. This postulate states that "If B lies between A and C, then the length of AB = the length of BC" 29. a statement accepted without proof 30. the course you are studying 31. If p then q, this would be wrtten as if q then p. 32. A pair of angles whose sum is 180 degrees are this
