Question

Ques: the perimeters of two similar triangles are 30 cm and 20 cm. if one side of the first triangle is 12 cm, determine the corresponding side of the second triangle.

Answer 1

If two triangles are similar then ratio of the perimeters of the triangles is equal to the ratio of their corresponding sides.

Let the required side be 'x'

Following this theorem, just plug the values

30/20 = 12/x
3/2 = 12/x
x = 24/3
x = 8

So required value of the corresponding side is 8 cm
