Please help! The answer is not A I got this question wrong.
Veronika [31]

Answer:

Right option is (D).

ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.

Step-by-step explanation:

We have given,

Two triangles ΔABC and ΔDBE such as :

\frac{BD}{BA} =\frac{BE}{BC}

This relation will contribute to side side similarity.

Also,

∠B = ∠B  , This will contribute as an angle similarity .

So combining above two relations,

\frac{BD}{BA} =\frac{BE}{BC}

and ∠B = ∠B

we can conclude that the triangle  ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.

Hence the right option is (C)
