A rectangle with four congruent sides.

A rectangle with four congruent sides.

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

Answer: (D)

A square is a special kind of quadrilateral that has both properties: all angles are right angles (like a rectangle) and all sides are congruent (like a rhombus). So when you’re told to identify a rectangle with four congruent sides, you’re describing a figure that satisfies both conditions, which is exactly a square. The option describing a rectangle captures the right-angle feature but doesn’t require equal sides. The option describing a rhombus has equal sides but doesn’t require right angles. The trapezoid has only one pair of parallel sides and doesn’t specify equal sides or right angles. Therefore, the square is the correct fit.
