                    Example.  Here are some 4-sided shapes.
                                 a.     Which types of polygons are these?

                                 b.     In  what ways are a rectangle
                                        and a square different from these
                                        shapes?

                    Solution.  a.       All the 4-sided polygons are called quadrilaterals.
                                 b.     All the angles of a rectangle and a square are right angles, but the

                                        angles of these quadrilaterals are acute and obtuse angles.
