16. In the 6th century, a Greek, named Pythagoras,

discovered the sides of a right triangle have a

definite relationship to each other. That relationship

is stated as follows:

THE SQUARE OF THE HYPOTENUSE IS EQUAL

TO THE SUM OF THE SQUARES OF THE OTHER

TWO SIDES.

The sum of the squares of the base and the altitude

of a right triangle is equal to the square of the

17. Let's review. The basic formula for the Pythagorean

theorem is stated:

a2+ b2 = c2 .Variations of the basic formula permit

solution for the unknown side of right triangles when

ANY TWO sides are known.

To solve for hypotenuse, when

base and altitude are known.

To solve for altitude, when base

and hypotenuse are known.

To solve for base, when altitude

and hypotenuse are known.
