Answer:
Option A
Explanation:
Here we need to tell which could be the side lengths of a right angled triangle . As we know that in a right angled triangle , the sum of square two sides along the right angle is equal to the square of side opposite to right angle .
That is ,


We can start by looking at the options , first option is ,

So by squaring first two sides and adding them , we have ,


And by squaring the third side we have ,

Hence here the sum of square of two sides is equal to the square of third side .
Therfore the triangle with sides √48 in , √12in and √60 forms a right angle ∆.
