Are all squares parallelograms? Yes. All squares have equal angle measures of 90 degrees which makes the opposite sides parallel.

Every quadrilateral is a parallelogram? No. A trapezoid is a quadrilateral but is NOT a parallelogram (there are two sides that are NOT parallel).

If a quadrilateral is a square, then it is a rhombus? Yes. All squares are rhombi (since all squares have equal side lengths).
