+## Complementary and Supplementary Angles
+A **complimentary** angle is formed when two positive angles 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.

+A **supplementary** angle is formed when two positive angles add up to $180\degree$ or $\pi$. One mnemonic device that you can use to remember this is:

+Angles greater than $90\degree$ have no complement and angles greater than $180\degree$ have no supplement.

| Terminal side | In standard position, the terminal side is the ray that's being measured relative to the initial side. |
| $s$ | The length of a curve along the radius. |
| 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. |
