The scale factor of a similar triangles=
Length of first triangle's side / Length of second triangle's side
4 / 5 = 0.8
12 / 15 = 0.8
20 / 25 = 0.8
So the scale factor of the similar triangles is 0.8
Solve the problem show the solution
Find the scale factor of a similar triangle whose sides are 4,12,20 and 5,15,25
