In this video, I discuss two special right triangles, how to derive the formulas to find the lengths of the sides of the triangles by knowing the length of one side, and then do a few examples using them!
Knowing the corresponding side lengths for these special right triangles is very useful to have memorized but dont forget that you can always derive them quickly in a pinch.
For those of you who go on to take PreCalculus or Trigonometry, knowing the propertie of these two triangles is useful as they will come up very often in a variety of applications.
