Best Answer

To be a parallelogram, the figure needs both sets of opposite sides to be parallel. A rectangle needs to have four right angles. This means the rectangle has to be a parallelogram. However, you can have opposite sides parallel without having right angles, as long as opposite angles are equal to each other,

Can a parallelogram be a rectangle and a square?

the three special quadrilaterals that can be a parallelogram are a rectangle, a square, and a rhombus Actually, this is incorrect. All squares are rectangles. All rectangles are parallelograms. Therefore all squares are parallelograms. But not all parallelograms are rectangles. And not all rectangles are squares.
