  1. 4. A type of conic section or symmetrical open curve. The ___________ is the set of all points in a plane, the difference of whose distance from two fixed points in the plane is a positive constant.
  2. 8. Two adjacent angles whose non-common opposite sides form opposite rays.
  3. 10. An infinitely thin and infinitely long collection of points extending in two opposite directions.
  4. 14. A mathematical equation expressing inequality and containing a greater than (>), less than (
  5. 16. A geometric figure made up of two rays that have a common endpoint called the vertex.
  6. 18. Where the graph crosses the y-axis, and is represented by an order pair. Set x=0 to solve!
  7. 21. The highest or lowest point on the graph. Located on the axis of symmetry, and is represented by an order pair.
  8. 22. y=a(x-h)^2 + k
  9. 24. A semi-circle device used for measuring angles. The edge of a protractor is subdivided into degrees.

  13. 32. Equations that are functions can be written in a form called ______________.
  14. 33. Two angles whose measurements add up to 180 degrees.
  15. 34. consists of two endpoints and all points of the line between the two endpoints.
  16. 35. The study of lines, angles, shapes, and their properties.
  17. 37. Two angles whose measurements add up to 90 degrees.
  18. 38. An exponent that is written as a fraction.
  19. 40. Bisector, A line, segment, or ray that intersects a segment at its midpoint and forms four right angles.
Down
  1. 1. Part of a line that has only one end point and goes on infinitely in only one direction.
  2. 2. A closed figure made up of line segments in a two-dimensional plane.
  3. 3. Lines that never intersect; they go in the same direction, the same distance apart and have the same slope.
  4. 5. An angle equal to 90°.
  5. 6. Integers that come right after each other. (1,2,3)
  6. 7. An equation that can be written with one side equal to 0. Quadratic equations ask you to find the quadratic polynomial that is equal to zero.
  7. 9. A comparison of two quantities.
  8. 11. A vertical line that cuts through the vertex.
  9. 12. A line, segment, or ray that hits a vertex and cuts the line./seg./ray into two congruent angles.

  11. 15. A segment joining the midpoints of two sides of a triangle.
  12. 17. Two angles who share a common vertex and whose non-common sides form opposite rays.
  13. 19. Inequality Theorem, The sum of the lengths of any two sides must be greater than the length of the third side.
  14. 20. As the independent value increases the dependent value decreases (as the independent value decreases the dependent value increases): it has an opposite effect.
  15. 23. A quantity that is not whole that contains a numerator and denominator.
  16. 24. A statement that two ratios are equal.
  17. 25. Two non-overlapping angles that share a common side and common vertex.
  18. 26. As the independent value increases (or decreases) the dependent value increases (or decreases): it has the same affect
  19. 27. A line that crosses/intersects two or more lines.
  20. 29. Integers that are odd integers that come right after each other. (1,3,5)
  21. 36. Two lines that intersect to form four right angles;slopes are negative reciprocals; form adjacent congruent angles.
  22. 39. A number squared is multiplied by itself; whatever integer gives the original number when multiplied by itself. For instance, 12 x 12 or 12 squared is 144, so the _____________ of 144 is 12.
