In these lessons, we will learn the names of the sides of a right triangle hypotenuse, adjacent, opposite and how they are used in trigonometry. Example: Identify the hypotenuse, adjacent side and opposite side in the following triangle: a for angle x b for angle y.
The first part of this video will explain the difference between the hypotenuse, adjacent and opposite sides of a right triangle. With trigonometry, you always work in right-angled triangles. In these triangles you have three sides, of which two intersect at a right angle. These sides are called shorter sides.
The shorter side that is opposite of the angle you look from is called the opposite shorter side. This side is not an arm of the angle you are looking from. The shorter side that is intersecting with the angle you look from is called the adjacent shorter side.

This is not a homework question I know that in a degree right triangle, the relationship is 1, square root of 3, and the hypotenuse is two.
I also understand the following: Sine is Opposite over Hypotenuse Cosine is Adjacent over Hypotenuse Tangent is Opposite over Adjacent The main thing I have a problem with is determining which sides are what; which one is opposite and which one is adjacent.

The other sides depend on which angle you are interested in.
Usually called A The final angle is the one opposite the angle you chose to label the sides with.
