A rectangle is a four-sided polygon, or quadrilateral, with opposite sides that are equal in length and four right angles. This unique structure allows rectangles to be classified as a specific type of parallelogram, which has distinct properties that set them apart from other quadrilaterals. Rectangles play a vital role in geometry due to their prevalence in everyday life and their connection to other special parallelograms like squares and rhombuses.
