Properties of similar triangles are given below, Similar triangles have the same shape but different sizes. A polygon consists of straight edges and at least three vertices. Remember that the ratio of perimeters of two similar polygons is equal to their scale factor. Now that we have obtained the value of the shorter side create a proportion formula for the side lengths and corresponding segments such as medians and angle bisectors. First, let us get clear with what similar means. The following formulas were used to develop calculations for this calculator where a = side length, r = inradius (apothem), R = circumradius, A = area, P = perimeter, x = interior angle, y = exterior angle and n = number of sides. Area is a quantity that describes the size or extent of a two-dimensional figure or shape in a plane. Given that PQRS ~ JKLM, find the following.
