How many triangles can be formed with sides of length 4 cm, 5 cm, and 10 cm?

  • A.0
  • B.1
  • C.2
  • D.Infinite

Answer: A

To form a triangle, the Triangle Inequality Theorem must be satisfied. The sum of any two sides must be greater than the third side.

Let's check:

4 + 5 > 10? => 9 > 10. This is false.

Since the condition is not met, no triangle can be formed with these side lengths.
