State true or false: All squares are not parallelograms.A. trueB. falseC. ambiguousD. data insufficient

The correct answer is B. false.

Explanation: A square is a special type of parallelogram. By definition, a parallelogram is a quadrilateral where opposite sides are parallel and equal in length. A square satisfies this condition because its opposite sides are parallel, equal in length, and its angles are all 90 degrees. In fact, a square is a specific case of a rhombus (where all sides are equal) and a rectangle (where all angles are 90 degrees), both of which are parallelograms. Therefore, the statement "All squares are not parallelograms" is false.

So, the answer is false.
