Question

in triangle ABC if DE||BC BPT​

Answer 1

$\Huge\sf\mathbb\color{blue}\underline{\colorbox{b}{Answer}}$

From the question it is given that,

DE∥BC and BD=CE

So, we have to prove that ABC is an isosceles triangle.

Consider the triangle ABC,

AD/DB=AE/EC

Given, DB=EC … [equation (i)]

Then, AD=AE … [equation (ii)]

By adding equation (i) and equation (ii) we get,

AD+DB=AE+EC

So, AB=AC

Therefore, △ABC is an isosceles triangle.
