Not all parallelograms do but a rhombus does.
Four-sided figures are called quadrilaterals. They can be parallelograms, but do not have to be. They can be: square rhombus parallelogram quadrangle rhomboid rectangle oblong kite trapezium trapezoid
yes
It is a skew prism. If the parallelograms are rectangles then it is a right prism.
square and rhombus
All parallelograms are quadrilaterals but all quadrilaterals are not necessarily parallelograms
All 4 sided parallelograms are quadrilaterals.
All 4 sided parallelograms are quadrilaterals.
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.
Yes because all parallelograms have four sides. But the opposite is not true. There are some quadrilaterals that aren't parallelograms.
All parallelograms are in the class of 4 sided quadrilaterals.
Yes all parallelograms are 4 sided quadrilaterals.
parallelograms and,or quadrilaterals
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.
Parallelograms!
no, but all parallelograms are quadralaterals.
No, all quadrilaterals are not parallelograms.
