To determine if the lengths of 3 feet, 4 feet, and 5 feet can form a triangle using the Triangle Inequality Theorem, we need to check the following conditions:
- \( a + b > c \)
- \( a + c > b \)
- \( b + c > a \)
Let’s assign:
- \( a = 3 \)
- \( b = 4 \)
- \( c = 5 \)
Now, we check each condition:
- \( 3 + 4 > 5 \) (True, since 7 > 5)
- \( 3 + 5 > 4 \) (True, since 8 > 4)
- \( 4 + 5 > 3 \) (True, since 9 > 3)
Since all three conditions are satisfied, we can conclude that the lengths 3 feet, 4 feet, and 5 feet do indeed form a triangle.
The correct response is: Yes, because the sum of any two sides is greater than the third side.
