In Euclidean plane geometry, a rectangle is any quadrilateral with 4 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 4 sides of equal length is a square. The term oblong is occasionally used to refer to a nonsquare rectangle.. A rectangle with vertices ABCD would be denoted as Rectanglen..Rectangles are involved in many tiling problems,such as tiling the plane by rectangles or tiling a rectangle by polygons..A rectangle is cyclic..all corners lye on a single circle..The British flag theorem states that with vertices denoted A, B, C, and D, for any point P on the same plane of a rectangle..A characteristic property of hyperbolic geometry is that the angles of a triangle add to less than a straight angle, or 180°. In the limit, as the side lengths approach infinity, there are even ideal hyperbolic triangles in which all 3 angles are 0°...
