A polygon with six or more sides, in which four of the angles are right angles and the other angles are not. These others are of any type - as required. It cannot be a pentagon because, if 4 angles are right angles, the fifth would be 180 degrees!

A rectangle and a square are two types of quadrilaterals having four equal angles, where each of them equals a right angle.
They are squares and rectangles that each have four congruent angles of 90 degrees which makes up a total of 360 degrees.
