No, a rectangle is not a figure with no angles. A rectangle is a quadrilateral with four right angles. Each angle in a rectangle measures 90 degrees. If a figure has no angles, it would be a circle, which has no straight lines or angles.
A polygon is a plane figure with 3 or more straight sides and angles. A plane figure is a flat enclosed figure made of straight lines, curved lines, or both.
