What is the name of a flat shape with 4 equal straight sides?

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

Answer: (C)

The name of a flat shape with four equal straight sides is a square. A square is a specific type of quadrilateral that not only has four equal sides but also four right angles. This definition encapsulates its unique characteristics that differentiate it from other shapes. While a rhombus also consists of four equal straight sides, the angles in a rhombus are not necessarily right angles; they can be angled differently, leading to distinct properties. A rectangle features opposite sides that are equal and has four right angles but does not require all sides to be equal. A parallelogram, which has opposite sides that are equal and parallel, could have unequal angles and sides. Therefore, the correct identification of the shape with four equal sides, specifically having right angles and equal lengths, is accurately defined as a square.
