1) Which set of three lengths can be the measures of the sides of a
triangle? *
What’s the answer

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.
A+B>C
