Answer 1

To determine if the side lengths 6 cm, 8 cm, and 10 cm can form a triangle, we can use the triangle inequality theorem. The theorem states that for any triangle with sides \( a \), \( b \), and \( c \):

1. \( a + b > c \)
2. \( a + c > b \)
3. \( b + c > a \)

Let's check the three inequalities with the given side lengths:

1. \( 6 + 8 = 14 > 10 \) (True)
2. \( 6 + 10 = 16 > 8 \) (True)
3. \( 8 + 10 = 18 > 6 \) (True)

Since all three conditions are satisfied, the side lengths 6 cm, 8 cm, and 10 cm will form a triangle.

The correct response is: They will form a triangle because the sum of any two of the side lengths is greater than the length of the third side.
