The
right triangle is one of the most important geometrical figures, used
in many applications for thousands of years.

A Greek mathematician
named Pythagoras developed a formula, called the Pythagorean
Theorem, for finding the lengths of the sides of any right triangle. He
treated each side of a right triangle as though it were a square and discovered
that the total area of the two smaller squares is equal to the area of the
largest square. He wrote this discovery as a formula:

where c is the
hypotenuse
and a and b are the other two legs
of the triangle. Move your mouse over the triangle to
