Which statement describes a rectangle?

• A. A quadrilateral with four right angles.
• B. A quadrilateral with opposite sides parallel.
• C. A polygon with four equal sides.
• D. A trapezoid with two right angles.

Answer: (A)

A rectangle is defined by having all four interior angles as right angles. The statement describing a quadrilateral with four right angles matches exactly what makes a rectangle. When every corner is 90 degrees, the shape fits the rectangle criteria. The other descriptions don’t pin down a rectangle specifically. A quadrilateral with opposite sides parallel describes a parallelogram, which includes rectangles but isn’t limited to them. Four equal sides describe a rhombus (or a square, which is a special rectangle), but four equal sides alone don’t ensure right angles. A trapezoid with two right angles has only two right angles, so it isn’t a rectangle.
