Marisol is given the following three lengths of a possible triangle: 1, 2 and 7. Would these side lengths form a triangle?
Yes, because 1 + 2 > 7, 2 + 7 > 1 and 7 + 1 > 2.
Yes, because 1 + 2 1 and 7 + 1 is greater than 2.
No, because 1 + 2 < 7 and in order for side lengths to meet the Triangle Inequality Theorem, any two side lengths must be greater than the third side when added together.
