Question

if ABC and DEF are two triangles and AB/DE = BC/FD then two triangles are similar if
a) Angle A = Angle F
b) Angle B = Angle D
c) Angle A = Angle D
d) Angle B = Angle E​

Answer 1

Answer:

∠B=∠D

Step-by-step explanation:

Given

DE

AB

=

FD

BC

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
