Across
  1. 4. an angle that is formed between the horizontal line and the line of sight
  2. 6. measures the space needed to cover the outside of a three-dimensional shape
  3. 8. the ratio of the length of the opposite side to the length of the adjacent side
  4. 10. the distance from the center of a circle or sphere to its edge or boundary
  5. 12. the measurement of the distance between two points
  6. 14. the amount of space occupied by a three-dimensional objec

  6. 9. a figure formed by two lines or rays that meet at a common endpoint
  7. 11. an angle that measures less than 90 degrees
  8. 13. a polygon with three sides having three vertices
  9. 15. the angle measured clockwise from the north line
  10. 17. the ratio of the side of the triangle opposite the angle divided by the hypotenuse
