Rectangles are a subset of quadrilaterals and of parallelograms. Rectangles are perhaps one of the most commonly used and recognized polygons, both in your mathematics courses and in a wide variety of real life situations. On a large scale, rectangles are the primary design element in most architecture. On a smaller scale, you see them almost everywhere, including paper, books, picture frames, windows, and doors.
