### What are parrelograms?

Parallelograms are quadrilaterals (4 sided figuers) in which the opposite sides are parallel. Rectangles are special parallelograms with right angles at every vertex. So are squares. Think of rectangle pushed so it leans. That is what most people think of as a parallelogram.

Yes.

### Are all quadrilaterals also squares?

No. A quadrilateral is any four-sided figure. The sides do not have to be of equal length, and the angles do not have to be right angles. So, all squares are quadrilaterals because they have four sides), but not all quadrilaterals are squares.

Some are, and some are not. A parallelogram is a special kind of quadrilateral ... one in which every side is parallel to the one across from it. So all parallelograms are quadrilaterals, but there are also a lot of other quadrilaterals that are not parallelograms.

All quadrilaterals are 4 sided shapes which includes trapezoids.

### Is a quadrilateral a rectangle?

Not all quadrilaterals are rectangles. Some quadrilaterals are rectangles, and the rest are not. However, all rectangles are quadrilaterals.

### Are some squares and rectangles not quadrilaterals?

All squares and rectangles are quadrilaterals. The of quadrilateral is a four sided figure. A square has four congruent sides, hence all squares are quadrilaterals. A rectangle is a four sided rhombus, so it is also a quadrilateral.
