True or False: The midpoint $M$ of a line segment $AB$ is the only point on the infinite line passing through $A$ and $B$ that is equidistant from both endpoints $A$ and $B$.

True or False: Squaring both sides of an equation is an equivalence transformation because it preserves the exact solution set of the original equation.
