+These rules apply regardless of the orientation of the triangle.

+Cosecant, secant, and tangent are inverses of sine, cosine, and tangent respectively, and so they can be found by taking $\frac{1}{x}$, where $x$ is the function you'd like to find the inverse of.

| Radian | Denoted with $rad$, one radian is equal to the radius, but it's measured along the arc in a curve instead of from the center. |
| Complementary Angles | Two positive angles that add up to $90\degree$ or $\frac{\pi}{2}$. One mnemonic device that you can use to remember this is:
Complementary starts with C, and C stands for corner. $90\degree$ makes a corner. |
| Supplementary Angles | Two positive angles that add up to $180\degree$ or $\pi$. One mnemonic device that you can use to remember this is:
Supplementary starts with S and S stands for straight. $180\degree$ makes a straight line. |
