if the parameters of two similar triangles ABC and d e f are 50 cm and 70 cm respectively and one side of triangle ABC = 20 CM then find the corresponding side of triangle d e f Share with your friends Share 2 Varun Rawat answered this We have,∆ABC~∆DEF givenPerimeter of ∆ABC = 50 cmPerimeter of ∆DEF = 70 cmLet AB = 20 cm; DE = ?We know that ratio of perimeters of 2 similar ∆'s is equal to the ratio of their corresponding sides.Now, Perimeter of ∆ABCPerimeter of ∆DEF = ABDE = BCEF = ACDF⇒Perimeter of ∆ABCPerimeter of ∆DEF = ABDE⇒5070 = 20DE⇒DE = 140050 = 28 cm 3 View Full Answer Viv E K answered this Hope!
