Across
  1. 4. the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point.
  2. 9. exterior a pair of angles that are outside the two parallel lines but on either side of the transversal
  3. 10. a trigonometric function that for an acute angle in a right triangle is the ratio of the side opposite the angle to the hypotenuse
  4. 11. a set of numbers that specify the position of a point in a coordinate system
  5. 13. one side of a polygon, usually used as a reference side for the other measurements
  6. 15. an expression of more than two algebraic terms
  7. 16. the size of one object in relation to other objects in a design, drawing, or model
  8. 17. a term with a fixed value in an expression or equation.
  9. 18. the angles formed when a transversal intersects two coplanar lines.
Down
  1. 1. two angles that are side by side and share a common vertex and a common side
  2. 2. the complete distance around a circle
  3. 3. identical
  4. 5. equals 180
  5. 6. the ratio of the length of the adjacent side to that of the longest side i.e. the hypotenuse.
  6. 7. the distance from the center a circle to any point on its circumference
  7. 8. a number between 1 and 0 used to qualify likelihood for processes that have uncertain outcomes
  8. 11. a letter or number representing a numerical quantity that multiplies a term
  9. 12. A number the relates the quantities or measures within a given situation with a multiplicative relationship
  10. 14. the ratio of the side opposite the angle we know, or want to know, over the side adjacent to that angle
  11. 15. a closed plane figure with at least three straight sides and angles
