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

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.
