Best Answer

A square or a rhombus. A rhombus does not have 4 congruent angles as a square does.

It's always a rhombus. And, depending on the angles, it could also be a square.

(This definition treats the square as a special case of the rhombus.)

No. In a regular polygon, all sides are congruent, and all angles are congruent. A parallelogram doesn't satisfy either of these conditions.No. In a regular polygon, all sides are congruent, and all angles are congruent.

Yes, in a sense.

A parallelogram with four congruent sides may be either a square or a rhombus.

A square

The definition of a parallelogram is that it has four sides, the opposite sides are congruent and parallel, and opposite angles are congruent. This includes rectangles, squares, rhombuses, etc.The definition of a rhombus states that it is a parallelogram, but more specifically that all sides are congruent.So a rhombus is a parallelogram, but not all parallelograms are rhombuses.

a parallelogram, rectangle, rombus, and square all are quadrilaterals. a quadrilateral means a shape with 4 sides. only 2 sides are congruent in a parallelogram 2 sides are congruent in a rectangle 4 sides are congruent in a rombus 4 sides are congruent in a square

Yes. That would make all sides congruent; in this case, your parallelogram would be a rhombus.

A parallelogram which has all congruent sides and angles is a square.

A square is the parallelogram that has all sides congruent. A square also has four angles that are all right angles.

No! A heptagon has 7 sides, a parallelogram has 4.

A parallelogram with 4 congruent sides is known as a rhombus.

A rhombus is a quadrilateral that has four congruent sides. It makes a parallelogram. Not all parallelograms have 4 congruent sides. Some have two pairs of opposite sides congruent.

What? :D

All sides congruent = square Two pairs of mutually congruent sides = rectangle

Not necessarily.
