In any triangle, a side is longer than the difference between the other two. A side is also less the the sum of the other two. If these two rules are not obeyed then a triangle cannot be formed by those sides.
a = 10 cm. b = 7 cm.
Then c > 10-7 = 3 cm and also, c < 10+7 = 17 cm.
3 cm < the third side < 17 cm
a = 10 cm. b = 7 cm.
Then c > 10-7 = 3 cm and also, c < 10+7 = 17 cm.
3 cm < the third side < 17 cm
