→We need to have atleast three parameters to construct a triangle. But still there are certain limitations. The angle sum property of a triangle and the sum of any two sides of a triangle being always greater than the third side, play an important role in judging whether a triangle can be constructed or not.
Q.1. If the lengths of two sides of a triangle are 14 cm and 18 cm, then the length of the third side can be :
(a) 32 cm$\quad$(b) 5 cm$\quad$(c) 4 cm$\quad$(d) 3 cm
