Which term refers to a polygon where all angles are right angles?

• A. Parallel Lines
• B. Symmetry
• C. Rectangle
• D. Rectilinear Figure

Answer: (D)

All interior angles being right angles means every corner is 90 degrees, which makes the shape a rectangle. A square is also a special case of a rectangle. A rectilinear figure describes a polygon whose sides are horizontal or vertical, but that can include corners that are 270 degrees as well, so not every angle is necessarily a right angle. So the term that best describes a polygon with all angles as right angles is rectangle. The other terms don’t match that specific property.
