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.
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.
Rectangle
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.
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.

Supplementary.
A polygon; specifically a tetragon. A two-dimensional shape with four equal sides and four right angles is a square. A two-dimensional shape with two sets of equal sides and four right angles is a rectangle. A two-dimensional shape with two sets of equal sides and two sets of equal angles is a parallelogram. A parallelogram where each opposite angel bisects the shape is a rhombus. A two-dimensional shape with one set of equal, parallel sides and two sets of equal angles is a trapezoid. A three-dimensional shape with four triangular faces is a tetrahedron.
