Question

Which of the following can be the side lengths of a triangle?

A-6,6,5
B-3,10,7
C-7,2,5
D-2,8,5

Answer 1

To solve this question, we need to know the triangle inequality property, which states that the sum of two legs of a triangle is always greater (it can't be equal to) than the third leg. Using this property, we can deduct that the only answer that works is A, 6,6, and 5.
