Pythagorean Theorem
In any right triangle, the sum of the square of the two perpendicular sides is equal to the square of the longest side. For a right triangle with legs measures a and b and length of hypotenuse c, the theorem can be expressed in the form:
c^2=a^2+b^2
see attached:
Area of the large square = Area of four triangles + Area of small square
A[total]=A[four-triangles]+A[small square]
(a+b)^2=4((1/2)ab)+c^2
a^2+2ab+b^2=2ab+c^2
a^2+b^2=c^2
