| reference angle | the angle we are referring to when labeling opposite and adjacent sides of a right triangle |
| opposite side | the side of a right triangle opposite the reference angle |
| adjacent side | the side of a right triangle next to the reference angle |
| hypotenuse | the side of a right triangle opposite the right angle; the longest side of a right triangle |
| Pythagorean Theorem | the sum of the lengths of the two legs of a right triangle squared is equal to the length of the hypotenuse squared; resulting in the formula a^2 + b^2 = c^2, where c is the length of the hypotenuse |
