A quadrilateral is any plane figure bounded by four straight lines.
There are no conditions in this definition that specify if any or all of the lines are of equal length or parallel, or if any or all of the interior angles are equal. When these conditions are applied then the quadrilateral so formed is usually given a special name.
A rectangle is a special type of quadrilateral. It has both pairs of opposite sides parallel, opposite sides are of equal length and each of the vertex (interior) angles equals 90°.
All quadrilaterals are therefore not rectangles - just some of them.

Are all rectangles quardilatrals?
Yes all rectangles are quadrilaterals.
Are all rectangles quadrilaterals and why?
Yes, all rectangles are quadrilaterals because they have four sides and all quadrilaterals have four sides.
Are all square also rectangles?
All squares and rectangles belong to the class of 4 sided quadrilaterals
What are quadrilaterals that aren't rectangles?
Squares, parallelograms, rhombuses, and trapezoids are quadrilaterals that are not rectangles.
Is quadrilateral a parallelogram?
Not necessarily. All parallelograms are quadrilaterals but not all quadrilaterals are parallelograms. Parallelograms are more specific instances of quadrilaterals. Its like saying all squares are rectangles but not all rectangles are squares.
Are some rectangles quadrilaterals?
All rectangles are quadrilaterals. A quadrilateral has 4 sides; all rectangles have 4 sides; thus all rectangles are quadrilaterals.
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 all rectangles quadrilites?
All rectangles are quadrilaterals.
Are all rectangles quardilatrals?
Yes all rectangles are quadrilaterals.
Are all rectangles quadrilaterals and why?
Yes, all rectangles are quadrilaterals because they have four sides and all quadrilaterals have four sides.
Are all square also rectangles?
All squares and rectangles belong to the class of 4 sided quadrilaterals
All rectangles are?
parallelograms and,or quadrilaterals
All quadrilaterals are rectangles?
No, not all quadrilaterals are rectangles. Quadrilaterals are any shapes that have four angles and sides. While not all quadrilaterals are rectangles, all rectangles have to be quadrilaterals.No, but a rectangle is in the family of 4 sided quadrilateralsNo. A quadrilateral is a rectangle only if its angles are all equal.no
All rectangles are what kind of polygons?
All rectangles are quadrilaterals, and more specifically parallelograms.
What are the irregular quadrilaterals?
Rhombuses, rectangles, kites, parallelograms, and trapezoids are all irregular quadrilaterals.
What are quadrilaterals that aren't rectangles?
Squares, parallelograms, rhombuses, and trapezoids are quadrilaterals that are not rectangles.
Is quadrilateral a parallelogram?
Not necessarily. All parallelograms are quadrilaterals but not all quadrilaterals are parallelograms. Parallelograms are more specific instances of quadrilaterals. Its like saying all squares are rectangles but not all rectangles are squares.
