  1. 1. are congruent. Formally, ______ are defined as two exterior angles on opposite sides of a transversal which lie on different parallel lines.
  2. 2. An expression that can have constants, variables and exponents, that can be combined using addition, subtraction, multiplication and division, but no division by a variable, a variable's exponents can only be 0,1,2,3,... etc,it can't have an infinite number of terms.
  3. 4. a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide)
  4. 6. the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
  5. 8. the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
  6. 9. is a special relationship where each input has a single output.
  7. 12. the measuring (of angles and sides) of triangles. Historically speaking, the triangular approach to _______ is ancient, wheres the circular approach now taught in our schools is relatively recent.
  8. 13. moving a shape without rotating or flipping it.
