As per the Third Side Rule of triangles: the third side of a triangle must always be less than the sum of the other two sides, and greater than the difference.

If the lengths of the sides of a triangle are a, b, and 7, which of the following could be the value of a – b ?

I. 4
II. 7
III. 12

A. I only
B. II only
C. I and II only
D. II and III only
E. I, II, and III


third side rule ; a+b>7
so a,b can be 6,1 or 11,7 difference = 4


for a-b=7 ; the value a,b has to be 14 ; a,b 8,1 ; 9,2 , 10,3 not possible
a-b= 12; a,b can be 14,2 , 15,3 value of third side ; 2,3 will be too short to meet and connect with 7

IMO A
