HELP ME OUT? For each set of three lengths, determine if they can be the side lengths of a triangle.

Answer 1

12, 13, 4

Sum of the squares of the smaller 2 sides < longest side squared - OBTUSE SCALENE TRIANGLE

6, 4, 11

LONGEST SIDE GREATER THAN OR EQUAL TO THE SUM OF THE OTHER TWO SIDES - NO TRIANGLE.

7, 6, 5

Sum of the squares of the smaller 2 sides > longest side squared - ACUTE SCALENE TRIANGLE

3, 14.5, 17
