Answer:
Option 2nd is correct that is side AB.
Explanation:
We are given a right angled ΔABC in which ∠A is right angle.
We have to find which side is opposite to ∠C
Since, ∠A is right angle it implies side CB is hypotenuse in ΔABC.
We know that side which are opposite to a angle does not includes the vertex of that angle.
like above hypotenuse is opposit of ∠A and name of hypotenuse does not have vertex a in it.
Similarly Side opposite to ∠C will not have vertex C in it.
So, AB is the side opposite to ∠C.
Therefore, Option 2nd is correct that is side AB.
