Answer: Yes
Explanation:
We can simply use the Triangle Inequality Theorem which states that the sum of 2 sides of a triangle is greater than the third side.
Therefore,
=> 4 + 6 = 10 (Greater than 9)
=> 6 + 9 = 15 (Greater than 4)
=> 4 + 9 = 13 (Greater than 6)
Hence the side lengths 4, 6, 9 can be used to form the sides of a triangle.
