- 33. sides add to 360
- 34. A quadrilateral where the opposite sides are paralell
- 36. If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then triangles are congruent.

- 39. A line, segment,ray,or plane that intersects at the midpoint of the segment.
- 40. corresponding parts of congruent triangles are congruent
Down
- 1. two angles in a plane that share a common vertex and a common side but no common interior points.

- 18. The intersection of all 3 angle bisectors
- 19. a rigid transformation in which all points of the pre-image slide the same distance in the same direction. (could also be called a glide).
- 23. A geometric figure which extends in two directions without ending. (lines dont have a beginning or end).
- 24. A portion of a line, it comes from a line and only goes infinitely in one direction.
- 25. If two angles are vertical, they are congruent.
- 29. If 3 sides of one triangle are congruent to 3 sides of another triangle, then the triangles are congurent.
- 30. Two objects that have the same size and shape. The symbol is a combination of = for the same size and ~ for a similar shape.
