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.
Its basically a hierarchy just for quadrilaterals.
Not all quadrilaterals are rectangles. Some quadrilaterals are rectangles, and the rest are not. However, all rectangles are quadrilaterals.
They are called Quadrilaterals.
Here are the quadrilaterals you are expected to know about.SquareRhombusRectangleParallelogramTrapeziumKite
There are no such shapes because all squares are quadrilaterals - by definition.

A pair of quadrilaterals, of any kind, will be similar if their sides are in some constant ratio - other than 1 - and their angles are the same.
Rectangles have only right angles (which means 90o angles) whereas quadrilaterals can have any kind of angles, as long as they have 4 sides.

All rectangles are quadrilaterals, and more specifically parallelograms.
A concave quadrilateral
Some are, and some are not. A trapezoid is a special kind of quadrilateral ... one in which two of the four sides are parallel. So all trapezoids are quadrilaterals, but there are also a lot of other quadrilaterals that are not trapezoids.
All kites are quadrilaterals, but quadrilaterals are not kites.
don`t know figure it out
All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms
