3. The vertex is at the origin and its initial side lies on the positive x-axis.
6. Consists of two rays with a common endpoint or two line segments with a common endpoint.
7. An angle (theta) is the positive acute angle made by the terminal side of angle (theta) and the x-axis.
10. A number that represents the result of counting, or a number that results from theoretical work and is not the result of a measurement.
19. The angle from the point X to point Y (below X) is the acute angle formed by ray XY and a horizontal ray with endpoint at X.
21. Angles which are opposite angles formed by intersecting lines.
23. The angle from point X to point Y (above X) is the acute angle formed by ray XY and a horizontal ray endpoint at X.
24. When a ray is rotated around its endpoint to form an angle, the ray in its location after rotation is the _________ _______ of the angle.
25. An angle that is formed by clockwise rotation around its endpoint.
26. Also called complements. Two positive angles with a sum of their measures equalling 90.
28. When a ray is rotated around its endpoint to form an angle, the ray in its starting position is called _______
29. Written as 1", is 1/60 of a minute.

1. An angel measuring more than 90 but less than 180.
2. An angle measuring between 0 & 90.
3. A digit which is obtained by actual measurement.
4. A unit of measure for angles. Represents 1/360 of a rotation.
5. The side of length y.
8. The function of pairs sine and cosine, tangent and cotangent, and secant and cosecant.
9. The endpoint of the ray that is rotated to form the angle.
11. An angle measuring exactly 180.
12. An angle that is formed by counterclockwise rotation around its endpoint.
13. Two angles that have the same initial side and the same terminal side, but different measures of rotation. The measures differ by a multiple of 360.
14. The side of length x.
15. An angle measuring exactly 90.
16. An angle that, when placed in standard position has its terminal side along the x-axis or the y-axis.
17. Triangles that are both the same size and same shape.
18. Triangles which are the same shape, but not necessarily the same size.
20. Two positive angles with a sum which measures 180.
22. Two rays or line segments.
27. Written 1', is 1/60 of a degree.
