Question

Which set of sides will make a triangle?
a: 10 cm, 9 cm, 9 cm
b: 6 cm, 15 cm, 6 cm
c 13 cm, 7 cm, 6 cm
4 cm, 8 cm, 14 cm

Answer 1

Answer:

part (a) is correct

a triangle is formed when sum of any 2 sides of a triangle is greater than the third side.

In all the three parts (except a) the sum of 2 sides is either smaller or equal to the third side. Therefore they do not form a triangle.

Hence part a is correct
