Answer 1

To determine which set of side lengths will form a triangle, we can use the triangle inequality theorem. According to this theorem, for three sides to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Let's analyze each set of side lengths:

1. 8, 6, 2

   • 8 + 6 > 2 (True)
   • 8 + 2 > 6 (True)
   • 6 + 2 > 8 (False)
   • This set does not form a triangle.

2. 4, 1, 6

   • 4 + 1 > 6 (False)
   • This set does not form a triangle.

3. 5, 2, 4

   • 5 + 2 > 4 (True)
   • 5 + 4 > 2 (True)
   • 2 + 4 > 5 (True)
   • This set forms a triangle.

4. 3, 3, 6

   • 3 + 3 > 6 (False)
   • This set does not form a triangle.

The only set of side lengths that can form a triangle is 5, 2, 4.
