**Quadrilaterals are any
polygons with four sides. While quadrilaterals can have all sides unequal and
all angles unequal there are some special kinds of quadrilaterals. They are
as follows:**

**A square is a quadrilateral
with four equal sides and four equal right angles. **

**A rectangle is a quadrilateral
wtih four equal right angles, and two sets of parallel opposite sides that are
equal.**

**A trapezoid is a quadrilateral
with two opposite sides parallel but not equal. **

**A parallelogram is a
quadrilateral that has two pairs of opposite sides that are parallel and equal
to one another. It differs from a rectangle in that its angles are not right
angles. A rhombus is an equilateral parallelogram, with all sides equal. **
