  1. 3. written 1’, is 1/60 of a degree.
  2. 6. one of the two rays (or line segments) with a common end-point that form an angle.
  3. 7. an angles vertex is at the origin and its initial side lies on the positive x-axis. Is said to lie in the quadrant its terminal side lies.
  4. 8. is an angle that is formed by counter clock-wise rotation around its endpoint.
  5. 9. is formed by rotating a ray around its endpoint
  6. 10. is an angle that, when placed in a standard position has its terminal side along the x-axis or the y-axis
  7. 12. triangles that are both the same size and the same shape are congruent triangles.
  8. 14. two positive angles are this (or complements) if the sum of their measure is 90 degrees.
  9. 16. A number that represents the result of counting, or a number that results from theoretical work and is not the result of a measurement.
  10. 20. from point X to point Y (above X) is the acute angle fromed by ray XY and a horizontal ray with endpoint at X.
  11. 23. is an angle measuring exactly 180 degrees.
  12. 24. is a digit obtained by actual measurement.
  13. 27. The length of side X adjacent to angle A
  14. 29. is an angle that is formed by clockwise rotation around its endpoint.
  15. 30. is an angle measuring exactly 90 degrees.
Down
  1. 1. when a ray is rotated around its endpoint to form an angle, the ray in its location after rotation is this term.
  2. 2. is an angle measuring more than 90 degrees but less than 180 degrees.
  3. 4. written 1”, is 1/60 of a minute.
  4. 5. is an angle measuring exactly 180 degrees.
  5. 7. two positive angles are this or supplements) if the sum of their measure is 180 degrees.
  6. 11. from point X to point Y (below X) is the acute anlge formed by ray XY and a horizontal ray with endpoint at X.
  7. 13. two angles that have the same initial side and the same terminal side , but different measrues of rotation. The measures differ by a multiple of 360 degrees.
  8. 15. are opposite angles formed by intersecting lines.
  9. 17. The reference angle for an angle Ø, written Ø’, is the positive acute angle made by the terminal side of angle Ø and the x-axis.
  10. 18. The function pairs sine and cosine, tangent and cotagent, and secant and cosecant are all this.
  11. 19. is a unit of measure for angles. One degree, represents 1/360 of a rotation.
  12. 21. is the endpoint of the ray that is rotated to form the angle.
  13. 22. triangles that are the same shape, but not necessarily the same size.
  14. 25. when a ray is rotated around its endpoint to form an angle, the ray in its starting position is this term.
  15. 26. The length of side Y opposite to angle A
  16. 28. is an angle measuring between 0 degrees and 90 degrees.
