<P> In Euclidean plane geometry , a rectangle is a quadrilateral with four right angles . It can also be defined as an equiangular quadrilateral , since equiangular means that all of its angles are equal ( 360 ° / 4 = 90 ° ) . It can also be defined as a parallelogram containing a right angle . A rectangle with four sides of equal length is a square . The term oblong is occasionally used to refer to a non-square rectangle . A rectangle with vertices ABCD would be denoted as ABCD . </P>
