Across
  1. 2. a proof that lists statements and reasons in a linear order, first to last, in columns
  2. 5. A quadrilateral with four right angles
  3. 6. add to 90
  4. 8. A triangle with all sides of equal length
  5. 10. If x=y then y can be substituted in for x in any expression
  6. 13. opposite over adjacent
  7. 14. adjacent over hypotenuse
  8. 16. Events that can never happen at the same time
  9. 17. If x=y and y=z, then x=z
  10. 19. If 2 sides are equal and angle between sides are equal, then the two triangles are congruent
  11. 20. if two hypotenuses and two legs are congruent, then the right triangles are congruent
  12. 21. a line segment that has both endpoints on a circle
Down
  1. 1. A quadrilateral with two pairs of parallel sides
  2. 3. The set of points equidistant from a central point
  3. 4. add to 180
  4. 7. if three sides are congruent, the triangles are congruent
  5. 9. A rectangle format that organizes data to examine the relationship between two categorical variables
  6. 11. opposite over hypotenuse
  7. 12. An angle in a circle with its vertex on the circle
  8. 15. a point that divides a line segment into two parts of equal length
  9. 18. The measure of any side or angle is equal to itself
