Across
  1. 1. d=2r
  2. 7. a positive whole number (1, 2, 3, etc.), sometimes with the inclusion of zero.
  3. 9. the pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal
  4. 10. a line that passes through two lines in the same plane at two distinct points in the geometry.
  5. 11. a number that is not a fraction; a whole number.
  6. 14. a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
  7. 16. the longest side of a right triangle, opposite the right angle.
  8. 19. a type of rigid geometrical transformation that maintains the object's size and shape
  9. 20. when one can become the other after a resize, flip, slide or turn.
  10. 22. the number which produces a given number when cubed.
  11. 23. formed when two lines intersect each other at a single point.
  12. 27. the product of a rational number multiplied by itself.
  13. 29. a number that can be used to measure a continuous one-dimensional quantity such as a distance, duration or temperature.
  14. 31. the amount of space occupied by a cone in a three-dimensional plane
  15. 32. a transformation of a shape in a plane that preserves length
  16. 35. the amount of space in it
  17. 37. a tool used for graphing points, lines, and other objects
  18. 39. Two angles that are exterior to the parallel lines and on the same side of the transversal line
  19. 40. a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression
  20. 41. the amount of space occupied, within the sphere
Down
  1. 2. not expressible as a ratio of two integers, and having an infinite and nonrecurring expansion when expressed as a decimal.
  2. 3. An image will reflect through a line, known as the line of reflection.
  3. 4. a number which produces a specified quantity when multiplied by itself.
  4. 5. one of a pair of angles on opposite sides of a line intersecting two other lines and outside the two intersected lines.
  5. 6. two angles that are on the interior of (between) the two lines and specifically on the same side of the transversal.
  6. 8. means to change
  7. 12. where a, b and c are the three positive integers.
  8. 13. the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

  12. 21. each of the pairs of opposite angles made by two intersecting lines.
  13. 24. a theorem attributed to Pythagoras that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
  14. 25. the ratio between the scale of a given original object and a new object
  15. 26. a number without fractions; an integer.

  19. 34. (of figures) identical in form; coinciding exactly when superimposed.
  20. 36. a number that is equal to the number, multiplied by itself, three times
  21. 38. ( of a number, quantity, or expression) expressible, or containing quantities that are expressible, as a ratio of whole numbers.
