7. In a 30° – 60° – 90° triangle, what is the ratio of the longer leg to the shorter leg? 8. In a 30° – 60° – 90° triangle. A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form a simple ratio, such as 45-45-90. This is called an "angle based" right triangle. A. Loading.
