**Right Triangle Properties**

A right triangle has one $$ 90^{\circ} $$ angle ($$ \angle $$ B in the picture on the left) and a variety of often-studied formulas such as:

- The Pythagorean Theorem
- Trigonometry Ratios (SOHCAHTOA)
- Pythagorean Theorem vs Sohcahtoa (which to use)

SOHCAHTOA only applies to right triangles (more here).
