  1. 6. A change in position or size of a shape in a coordinate plane. It includes translation, rotation, and reflection.
  2. 7. The magnitude of a real number without regard to its sign. It is also called a numerical value.
  3. 10. The measure of a line's inclination relative to the horizontal. You can get slope by dividing the rise over run.
  4. 15. The longest side of a triangle. It’s always the opposite side of the right angle.
  5. 16. The trigonometric function that is equal to the opposite side of a right triangle divided by the hypotenuse. It is also written as sin.
  6. 17. The name for Sine, Cosine and Tangent. You can use them to find the missing length for a triangle.
  7. 19. A type of transformation that takes each point in a figure and slides it the same distance in the same direction. In other words, it’s when a shape on a coordinate plane is being translated to another location.
  8. 20. A word for a particular order. Like a set, it contains numbers.

  6. 8. A mirror image of a function or object over a given line in the plane. In other words, it's when a shape on a coordinate plane is mirrored.
  7. 9. A formula to find out the unknown length of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
  8. 11. The trigonometric function that is equal to the opposite side of a right triangle divided by the adjacent side. It is also written as tan.
  9. 12. A numerical quantity that is not a whole number. It represents the portion/part of a whole thing.
  10. 13. The trigonometric function that is equal to the adjacent side of a right triangle divided by the hypotenuse. It is also written as cos.
  11. 14. A motion of a certain space that preserves at least one point. In other words, it's when a shape on a coordinate plane is rotated around a fixed point.
  12. 18. A rectangular array or table of numbers, symbols, or expressions. The number of rows and columns can vary.
