Across
  1. 2. The endpoint of the ray that is rotated to form the angle.
  2. 4. Opposite angles formed by intersecting lines.
  3. 5. Triangles that are the same shape, but not necessarily the same size.
  4. 7. 1/60 of a minute.
  5. 8. The function pairs sine and cosine, tangent and cotangent, secant and cosecant.
  6. 9. Two angles that have the same initial side and the same terminal side, but different measures of rotation, measures differ by a multiple of 360 degrees.
  7. 15. An angle that is formed by clockwise rotation around its endpoint.
  8. 17. From point X to point Y (below X) is the acute angle formed by ray XY and a horizontal ray with endpoint at X.
  9. 24. Formed by rotating a ray around its endpoint.
  10. 25. One of the two rays (or line segments) with a common endpoint that form an angle.
  11. 26. When the vertex of an angle is at the origin and its initial side is along the positive x-axis.
  12. 27. A unit of measure for angles, 1/360 of a rotation.
Down
  1. 1. The positive acute angle made by the terminal side of angle theta and the x-axis.
  2. 3. An angle measuring between 0 and 90 degrees.
  3. 5. A digit obtained by actual measurement.
  4. 6. An angle measuring exactly 90 degrees.
  5. 9. Two positive angles whose measures sum up to 90 degrees.
  6. 10. An angle measuring exactly 180 degrees.
  7. 11. A number that represents the result of counting, or a number that results from theoretical work and is not the result of a measurement.
  8. 12. Side of length Y.
  9. 13. An angle that is formed by counterclockwise rotation around its endpoint.
  10. 14. Triangles that are both the same size and the same shape.

  16. 21. The ray in its location after rotation when a ray is rotated around its endpoint to form an angle.
