One classic example of a paradox is the "liar paradox," which revolves around a statement that cannot consistently be true or false. An example would be the statement "This statement is false." If the statement is true, then it must be false, but if it is false, then it must be true, creating a paradoxical situation.
Since parallelograms are four sided figures where each pair of opposing sides are parallel, and squares are four sided figures with all sides and angels congruent, then anything which is a square must also be a parallelogram. The statement is therefore false.
Every statement apart from the axioms or postulates.
