Question

What makes a triangle a “special” right triangle? How can special right triangles help me find side lengths?

Answer 1

I think of a 30-60-90 triangle and a 45-45-90 triangle as special right triangles. See attached charts.

Answer 2

There are two "special" right triangles with which you need to be familiar; the 45º- 45º- 90º triangle and the 30º- 60º- 90º triangle. The "special" nature of these triangles is their ability to yield exact answers instead of decimal approximations when dealing with trigonometric functions.
