WebAnswer – To find the perimeter of a triangle with coordinates/vertices given, use the distance formula (x 2 – x 1) 2 + (y 2 – y 1) 2 . The perimeter of the given triangle is found to be 12 units. Explanation: Let’s begin by graphing the given triangle and labeling its vertices. Now, since the perimeter of a triangle is the sum of its sides: WebThe perimeter of Δ ABC is 24 inches, and the perimeter of Δ DEF is 12 inches. When you compare the ratios of the perimeters of these similar triangles, you also get 2 : 1. This leads to the following theorem. Theorem 60: If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.
