What is the correct identification of a rectangle?
Answer and explanation
Correct answer: Opposite sides are equal and parallel, and all angles are right angles
The correct answer is A. A rectangle is a quadrilateral, so it has four sides, and its defining property is that all four interior angles are right angles of 90 degrees. Its opposite sides are equal in length and parallel to one another. Option B describes the general property of a rhombus: all four sides are equal, but its angles do not have to be right angles. A square is a special rectangle because it also has four equal sides, but that does not make every rectangle a square. Option C describes a triangle, which has three sides, while option D describes a circle-like idea and has no relevance to a rectangle. Thus A gives the complete identification.
