square or rectangle.
parallelogram
A rhombus or a parallelogram
A parallelogram. More precisely, a non-rectangular parallelogram.
parallelogram
Yes it is. Also, there has to be 2 sets of equal length sides. Of course, there is 2 sets of sides with equal length every time unless it is a square.
Rectangle
There is nothing because if the shape has only four sides and that means two sets that are parallel, the angles will have to be right ones. Unless it's not a polygon that is. I take it back maybe a parallelogram.
A rectangle or a square are sets of quadrilaterals with two pairs of right angles. They each have two pairs of right angles and two sets of equal sides.
no
Supplementary.
It's not "can", it is simply "is". EVERY square is also a rhombus with right angles. A rhombus is simply a 4 sided polygon which has two sets of parallel sides which are all equal in length.
A square is a regular polygon with two sets of parallel sides. A parallelogram is an irregular polygon with one set of parallel sides. A rhombus is an irregular polygon with two sets of parallel sides. A rectangle is an irregular polygon with two sets of parallel sides. *Note - a regular polygon is a shape in which all sides are equal in length and all angles are equal in measurement.
