The proof of Pythagorean Theorem in a right angle,
the square of the hypotenuse is equal to the sum of the squares of the other two sides. States that in a right triangle that, the square of a (a2) plus the square of b (b2) is equal to the square of c (c2).
Hence
[tex]c^2=a^2+b^2\text{ }[/tex]Option D is the correct answer
