A circle? I'm not too positive on this.
The shape you are looking for is a quadrilateral. If you have a square, all angles MUST be right angles. A parallelogram can also have 4 equal sides in length and parallel sides, but a parallelogram doesn't have right angles.
Rectangle
rhombus
A sqare two pairs of parallel sides each corner is a right angle and all sides are equal.
a rectangle does not have four equal sides and its opposite sides are equal and has four right angles
A rhombus has 4 sides of equal length, opposing parallel sides, and no right angles

A square has 4 equal sides, 2 pairs of parallel sides and 4 right angles.
Rectangle
Yes because it has four egual right angles if it has four equal sides.
It has both but no right angles
A rhombus
A rhombus
a parallogram
A square
The quadrilateral described is a rectangle. In a rectangle, opposite sides are equal and parallel, and all four angles are right angles. This definition meets the criteria of having one pair of opposite sides that are equal and parallel, along with the presence of right angles.
