  1. 2. A transformation in which one point on the plane, the center of rotation, is fixed and everything else on the plane rotates about that point
  2. 4. When 2 angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the 2 triangles are congruent
  3. 7. Used to show 2 segments that bisect eachother being congruent
  4. 11. A line you add to a diagram to help explain relationships in proofs
  5. 13. A line, segment, or ray that is perpendicular to the segment at its midpoint
  6. 16. When 3 sides of one triangle are congruent to the three corresponding sides of another triangle, then they are congruent
  7. 22. A transformation that maps all points of a figure the distance in the same direction
  8. 24. A perpendicular segment from one vertex of the triangle to the opposite side or to the line that contains the opposite side
  9. 25. A diagram showing each statement leading to the conclusion
Down
  1. 1. A segment from one vertex of a triangle to the midpoint of the opposite side
  2. 3. When 2 angles of one triangle are congruent to 2 angles of another triangle, then the third angles are congruent
  3. 5. A pair of adjacent, supplementary angles
  4. 6. A transformation that stretches or shrinks the original figure
  5. 8. When 2 angles are non included side of one triangle are congruent to the 2 angles and corresponding nonincluded side of another triangle
  6. 9. When 2 sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the 2 triangles are congruent
  7. 10. When the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent
  8. 12. Non-coplanar, not parallel, do not intersect
