Trigonometry

3. rotation in clockwise direction
5. two angles in standard position with the same terminal side
11. the common endpoint
14. angles in standard position with terminal sides along the x-axis or y-axis
15. is formed when a ray is rotated around its endpoint
17. if the sum of the measures of two positive angles is 180 degrees
19. a triangle with no equal sides
20. an angle measuring greater than 90 degrees but less than 180 degrees
24. an angle measuring exactly 90 degrees
26. if its initial side is along the positive x-axis and its vertex is at the origin
27. the two other sides of the right triangle
28. if the sum of the measures of two positive angles is 90 degrees
29. a triangle with two equal sides
30. the longest side of a right triangle

1. is a straight path connecting two points
2. an angle formed by one complete counterclockwise rotation
4. are angles of equal measure that are opposite one another and share the same vertex
6. stems from the Greek word trigonon, which means "triangle"
7. an angle that has its vertex at the center of a circle
8. an alternate way of representing parts of degrees
9. a triangle with three equal sides
10. way of breaking down degrees
12. the portion of the line that starts at one point and extends to infinity
13. triangles with equal corresponding angle measures and corresponding equal side lengths
16. an angle measuring greater than 0 degrees but less than 90 degrees
18. is found by counting all of the digits from left to right starting with the first nonzero digit
21. one way to measure the size of an angle
22. the portion of the line between two points
23. an angle measuring exactly 180 degrees
25. rotation in a counterclockwise direction
