  2. 4. triangles that have the same shape but different size
  3. 6. part of a whole
  4. 8. two numbers written in a certain order surrounded by parentheses, usually (1st number, 2nd number).
  5. 9. comparison between the quantities with the same unit
  6. 11. the vertical axis of a coordinate system, along which the y-coordinates are measured.
  7. 12. ratio that represents between a model
  8. 14. the point (0,0) on the coordinate plane, where the x and y-axes cross.
  9. 15. all three sides a angle are equal.
  10. 17. ratio with a denominator of 1
  11. 18. an exact location in a plane or in space that has no size or dimension, only position.
Down
  1. 1. ratio between two varibles with a equilvent rates.
  2. 2. change in y over the change in the x or rise over run
