Question

Which set of three side lengths will NOT form a triangle?

Answer 1

B. 25, 38, 13 
These 3 will not form a triangle because the sum of the shorter sides must be greater than the longest side.
25 + 13 = 38 which is not greater than 38

Answer 2

B
25, 38, 13

25 + 13 = 38 (in a triangle the sum of two sides is always greater than the third side.)
