Which term is a parallelogram with four equal sides?

Which term is a parallelogram with four equal sides?

• A. Rhombus
• B. Parallelogram
• C. Rectangle
• D. Polygon

Answer: (A)

A shape that is a parallelogram with four equal sides is called a rhombus. A rhombus is a special kind of parallelogram where all four sides are the same length, and opposite sides are parallel. So it has the parallel sides part of a parallelogram plus the extra feature of equal side lengths. A parallelogram by itself has opposite sides parallel but not necessarily equal in length. A rectangle has four right angles, not necessarily equal sides. A polygon is any closed shape with three or more sides, not limited to parallelograms. A diamond-shaped figure is a common way to visualize a rhombus.
