All quadrilaterals are parallelograms?
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.
Are all parallelograms quadrilaterals?
Yes because all parallelograms have four sides. But the opposite is not true. There are some quadrilaterals that aren't parallelograms.
Which quadrilaterals have all the properties of a parallelogram?
Parallelograms!
Are all four sided shapes parallelograms?
No but they are all quadrilaterals
What property is true of all parallelograms?
They are quadrilaterals; opposite sides are parallel.
