Question

if in triangle ABC and DEF AB/DE = BC/FD then they will be similar when ​

Answer 1

Step-by-step explanation:

Given DEAB=FDBC 

Now if the angle made by both the sides of each triangle are equal to each other then triangle ΔABC and ΔDEF will become similar.

Hence ∠B should be equal to ∠D 

means ∠B=∠D
