Across
- 3. . is opposite to the angle
- 4. the longest side of a right-angled triangle, the side opposite the right angle\
- 7. the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to

Down
- 1. Hypotenuse/Opposite
- 2. always uses the x-axis as its frame of reference
- 5. . is the length of the opposite side divided by the length of the hypotenuse
- 6. is a branch of mathematics that studies relationships between side lengths and angles of triangles.
- 7. . is the length of the adjacent side divided by the length of the opposite side
- 8. The axes of a two-dimensional Cartesian system divide the plane into four infinite regions
- 11. fined as the ratio of a circle's circumference to its diameter
