Special Right Triangles - 45-45-90. The 45º- 45º- 90º triangle is one of two special right triangles we will be investigating.
The "special" nature of these triangles is their ability to yield exact answers instead of decimal approximations when dealing with trigonometric functions. Note: the legs need not be a length of 1 for these patterns to apply. The patterns will apply with any length legs. Lessonquiz_national. Really fucking useful.
