Question

The altitudes of two similar triangles are 30cm and 20cm respectively. If one side of first triangle is 12cm then determine the corresponding side of second triangle.​

Answer 1

please mark me as brainliest

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
