Sum of the lengths of any two sides of a triangle is always equal to the third side.
False
In order to form a triangle, there are two constraints on its sides:
1. The sum of any two sides must be greater than the third side.
2. The difference of any two sides must be less than the third side.
If the sum or difference becomes equal to the third side, then the sides will overlap each other and the triangle will not get formed.
Thus, the given statement is False.
