Sum of the angles of a square are equal to 360 degrees: ABC + BCD + CDA + DAB = 360. Although this formula is used for all quadrilaterals, for some quadrilaterals like square and rectangle, this formula can be simplified because in a square, all the sides are equal, so the perimeter formula becomes, a + a + a + a = 4a. In that case distance d is negative . The perimeter of a circle, often called the circumference, is proportional to its diameter and its radius.That is to say, there exists a constant number pi, (the Greek p for perimeter), such that if P is the circle's perimeter and D its diameter then, =.
