No but they are all quadrilaterals
You could use two isosceles triangles, or two parallelograms with one pair of sides half as long as the other, suitable trapeziums (trapezia?). There are also lots of irregular shapes.
No trapezoids are parallelograms, and no parallelograms are trapezoids.
Parallelograms are squares is sometimes true. Squares are parallelograms is always true. Rhomboids are parallelograms is also always true. So not all parallelograms are squares but some are.
In fact, some are rectangles, but not all are.
No because all 4 sided shapes are quadrilaterals which includes parallelograms
A square and a rhombus are two special forms of parallelograms.
parallelograms, and rectangles (parallelograms)
Geometric
A rectangle, square, rhombus, and rhomboid are all parallelograms.
Parallelograms.
no
Yes all parallelograms belong to the 4 sided shapes known as quadrilaterals
squares, rectangles, rhombuses
Parallelograms are 4 sided shapes that belong to the class of polygons known as quadrilaterals
No but they are all quadrilaterals
No, parallelograms are specific to quadrilaterals (shapes with 4 sides).
