However, sometimes the converse of a true statement is also true. For example, the Pythagorean theorem has a true converse: if \(a^2 + b^2 = c^2\text{,}\) then the triangle with sides \(a\text{,}\) \(b\text{,}\) and \(c\) is a right triangle. Whenever you encounter an implication in mathematics, it is always reasonable to ask whether the converse is true.
