To solve a right triangle means to calculate the lengths of any unknown sides and the measures of any unknown angles.

To solve a right triangle there must be three pieces of information known. The right angle must be known and either of the following

must occur:

• the lengths of two sides are known
• the length of one side and the measure of one other angle is known

The applet will calculate the length of any unknown side, or the measure of any unknown angle based on entered known information.
