Which of the following sets of numbers could be the lengths of the sides of a triangle ?
a) 2,4,6
b) 4,8,8
c) 8,3,6
d)12,8,3

If the sum of any 2 sides is equal to or less than the third side it is Not a triangle.

So A :- we have 2+4 = 6 so its not a triangle.

also D is not a triangle because 8+3 < 12

what about B and C?

In order to be the sides of a triangle, sum of any two sides must be greater than the third side

A:
2+4=6
B:
4+8>8
8+8>4
C:
8+3>6
8+6>3
6+3>8
D:
8+3<12

Hence, the correct options are B and C.
