Answer:
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
∠1>∠4 because Exterior angle is always greater than respective interior angle. Similarly, ∠2>∠3. Therefore ∠1>∠3 and BC>DC as size opposite to greater angle are also greater in length. Hence it is proved that either side of triangle is always greater than difference of remaining two sides.
