Question

if in two triangel A B C and D E F AB/EF=AC/FD=BC/ED then triangle ABC~​

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
