Across
  1. 2. two lines that intersect at a right angle
  2. 8. triangle in which all three sides have the same length
  3. 9. a statement created by flipping hypothesis and conclusion
  4. 11. figures that are the same size and shape
  5. 14. line, ray, or segment that divides a segment or an angle in two congruent parts
  6. 15. these two angles have a sum of 90 degrees
