CALCULUS Understanding Its Concepts and Methods

Pythagorean theorem

If
*a*,
*b*,
and
*c*
are the sides of a right triangle, and the angle between
*a*
and
*b*
is
90^{o},
then
*c*
is called the hypotenuse of the triangle.

The Pythagorean theorem says that
*c*^{2} = *a*^{2} + *b*^{2}.

The square on the hypotenuse is equal to the sum of the squares on the other two sides.
