. In a triangle ABC The relation which is true for its sides is
A. AB + BC < AC
B. AB + BC > AC
C. AB + BC = CA
D. AB = BC + AC
The sum of the two sides of a triangle is always greater than that of the third side.
The figure for a triangle ABC is
In the triangle, the sides are AB, BC, and AC.
So, the sum of AB and BC will be greater than AC.
Hence, the true relation will be
AB + BC > AC
The correct option is B, i.e. AB + BC > AC.
