What is the difference between the pythagorean theorem and the converse of the pythagorean theorem

The Pythagorean Theorem states that in a right triangle with legs a and b and hypotenuse c, a2 + b2 = c2.

The converse of the Pythagorean theorem states that, if in a triangle with sides a, b, c,

a2 + b2 = c2

then the triangle is right and the angle opposite side c is a right angle.
