If you know that a triangle is a right triangle you are able to use some simple methods to solve it. One of the simple methods is the pythagorean theorem.

-Pythagorean Theorem
A2 + B2 = C2
This is the formula for solving a basic right triangle. The A and B sides are the two smaller sides and C is the hypotenuse.external image PythagoreanTheorem16c.gif

Another way for solving a right triangle is using sin, cos, and tangent. An easy way to remember sin, cos, and tangent is
SOH- Sin is Opposite over Hypotenuse.
CAH- Cos is Adjacent over Hypotenuse.
TOA- Tangent is Opposite over Adjacent.
