  5. 15. a mathematical expression that contains two algebraic term that can be added, subtracted or multiplied
  6. 17. y=1/2x^2
  7. 18. a line segment or ray that hit a vertex and cuts the angle into congruent angles
  8. 19. part of a line that has one endpoint and goes on infinitely in only one direction
  9. 22. where it crosses the y axis
  10. 23. If an angle of one triangle is congruent to the corresponding angles and side lengths, then both the triangles are congruent.
  11. 25. two angles of one triangle are congruent to the corresponding angles of another triangle then the two triangles are similar(angle angle)
  12. 26. opposite side over hypotenuse
  13. 27. line lines that never intersects
  14. 28. interval going left to right y-values are decreasing
  15. 31. vertex line that cut graph in half
  16. 33. is an exponent that is written as a fraction
  17. 35. a geometric figure made up of two rays common endpoint called vertex
  18. 37. adjacent side over hypotenuse
  19. 38. form y=a(x-h)^2+k
  20. 40. when more or two variables are related directly
  21. 41. two angles whose measurement add up to 90
Down
  1. 1. where it crosses the x axis
  2. 2. involves a combination of direct or joint variation and inverse vsristion
  3. 3. y=ax^2+bx+c
  4. 4. a method allows you to convert from standard form to vertex form of a quadratic
  5. 5. two lines that intersect to form 4 right angles
  6. 6. (-∞,∞)
  7. 8. two angles whose measurement add up to 180

  9. 10. a line segment or ray that intersects a segment at its midpoint and forms 4 right angles
  10. 13. interval going left to right y-values are increasing
  11. 16. a line that intersects two or more lines
  12. 20. an infinitely thin and infinitely long collection of point extending in two opposite directions
  13. 21. after it gets on x how much you move on you y axis till vertex

  15. 29. Greatest common Factor
  16. 30. maximum or minimum point on the graph on axis if symmety
  17. 32. 3 side corresponding sides of two triangles are in proportion the triangles are similar
  18. 34. y=-x^2
  19. 36. consists of two endpoints and all point of the line between the two endpoint, the point in the middle of a line segment is called the midpoint
  20. 39. y=3x^2
