To determine if the lengths 4 inches, 8 inches, and 9 inches can form a triangle, we apply the Triangle Inequality Theorem. The theorem states that for any three sides of a triangle, the sum of the lengths of any two sides must be greater than the length of the remaining side. We will check the three conditions:
-
(True) -
(True) -
(True)
Since all three conditions are met, the lengths of 4 inches, 8 inches, and 9 inches can indeed form a triangle.
The correct response is: Yes, all of the conditions are met.
