Across
- 5. a line that intersects two or more lines in a plane at different points
- 9. points that lie in the same plane
- 10. a segment joining two consecutive vertices
- 12. congruent sides of a triangle
- 13. a line with a beginning but no end
- 14. angle/ 2 angle measures that sum to you 180
- 16. angle/ 2 angle measures that add up to 90
- 20. triangle/ all angles are acute
- 21. triangle/ one angle is right
- 22. triangle/ one angle is obtuse
- 23. triangle/ no sides are congruent
Down
- 1. part of a line
- 2. statement formed by negating both the hypothesis and conclusion of a converse of a conditional statement
- 3. property/ if a=b and b=c then a=c
- 4. triangle/ at least 2 sides are congruent
- 6. angles/ two nonadjacent angles formed by two intersecting lines
- 7. side opposite the vertex
- 8. part after then in conditional statemen
- 11. angle/ angle formed by the congruent sides
- 15. statement formed by interchanging the hypothesis and conclusion of the converse of a conditional statement
- 17. closed figure in a plane made up of segments
- 18. line/ line or line segment added to a diagram to help in a proof
