What do you know about the side lengths and trigonometric ratios in special right triangles

TEA [102]

Explanation:

This looks like an essay question with no right answer.

There are two "special" right triangles:

isosceles 45°-45°-90° triangle with sides in the ratios 1 : 1 : √2

30°-60°-90° triangle with sides in the ratios 1 : √3 : 2

These side lengths give rise to the trigonometric ratios shown below for angles with 30°, 45°, or 60° as reference angles.
