Which shape has four sides with opposite sides parallel and all angles right angles?

Which shape has four sides with opposite sides parallel and all angles right angles?

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

Answer: (B)

Identifying a rectangle: a quadrilateral with opposite sides parallel and four right angles. If a shape has two pairs of opposite sides that run parallel and every interior angle is 90 degrees, it fits the rectangle description. A square also meets these criteria and is a special kind of rectangle with all sides equal, but since the statement doesn’t require equal side lengths, the general category that matches the description is rectangle. The rhombus has equal sides but not necessarily right angles, so it doesn’t fit. The trapezoid has only one pair of parallel sides, so it also doesn’t fit.
