Question

triangle ABC~ triangle DEF,the AB /DE = BC /?​

Answer 1

EF

Step-by-step explanation:

By Thales Theorem or Basic Proportionality theorem, it is given that in similar Triangles the corresponding sides are proportional...

So, here it is given as ∆ABC ~∆DEF,

Therefore the proportional sides are AB <-> DE, BC <-> EF, AC <-> DF... Therefore,

$\frac{AB}{DE} = \frac{BC}{EF}$

Since the corresponding sides can only be proportional..
