What defines a rhombus?

• A. All angles are equal
• B. 4 equal sides
• C. 4 sides with 2 sides being equal
• D. A parallelogram with 4 equal sides

Answer: (D)

A rhombus is defined as a parallelogram with four equal sides. This means that all sides of a rhombus are of the same length, while also maintaining the properties of a parallelogram, where opposite sides are parallel and opposite angles are equal. This definition encompasses both the equal length of the sides and the parallel nature of the opposite sides. In addition to having four equal sides, a rhombus also possesses diagonals that bisect each other at right angles and bisect the angles of the rhombus itself. It is important to distinguish this shape from rectangles or squares, which also have equal sides but adhere to different angle properties. The other definitions provided do not apply to a rhombus specifically. While the option that states all angles are equal describes a square, which is a special type of rhombus, not all rhombuses have equal angles. The description of having four sides with two sides being equal does not accurately define a rhombus, as all sides must be equal in length. Identifying a rhombus solely based on four equal sides does not capture the defining aspect of its parallel structure as part of a parallelogram.
