  1. Question 4 : I disagree.

    The parallelogram has 1 pair of parallel lines, and it's opposite sides and angles are equal.A square can fit into these characteristics.

    However, a square has 2 pairs of parallel lines, and all its sides and angles are equal and a parallelogram does not necessarily have all these characteristics, and hence not all parallelograms are squares.
