We know that Triangle Inequality Theorem establishes that the sum of the lengths of any two sides of a triangle<span> is greater than the length of the third side </span>so case <span>A. 5M, 11M, 7M 5+11 > 7----> ok 11+7 > 5 ---> ok 5+7 > 11----> ok
case </span><span>B.10 m, 4 m, 5 m 5+4 > 10-----> is not ok
case </span><span>C.8 m, 4 m, 4 m 4+4 > 8----> is not ok
case </span><span>D.6 m,11 m, 5 m 6+5 > 11-----> is not ok
