Across
- 1. . a unit of measure for angles
- 4. Hypotenuse/Opposite
- 9. formed by two rays lie in a plane
- 10. the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to
- 12. angles who share the same initial side and terminal sides
- 13. is a unit of measure for angles used mainly in trigonometry. It is used instead of degrees.
- 14. the longest side of a right-angled triangle, the side opposite the right angle\
- 15. are a way of measuring an angle from a different direction
- 16. is a polygon with three edges and three vertices
- 17. is a branch of mathematics that studies relationships between side lengths and angles of triangles.
- 18. . is opposite to the angle
- 22. . is only a part of the area of an entire circle
Down
- 2. . is an angle of exactly 90°, corresponding to a quarter turn
- 3. The axes of a two-dimensional Cartesian system divide the plane into four infinite regions
- 4. is the length of the adjacent side divided by the length of the opposite side
- 5. Opposite / Adjacent
- 6. side is the side next to the angle in question
- 7. always uses the x-axis as its frame of reference
- 8. from Greek metron 'measure'
- 11. . is where the angle starts
- 19. fined as the ratio of a circle's circumference to its diameter
- 20. . is the length of the opposite side divided by the length of the hypotenuse
- 21. from Greek trigōnon, 'triangle'
- 22. . is a line that intersects a circle at two points
