Question

Can a triangle have the following side lengths? Explain.
5 feet, 2 feet, 10 feet

Answer 1

No, this can not be a triangle because if you use the Pythagorean theorem 5 squared plus 2 squared doesn't equal 10 squared.

Explanation:

You take 5 squared and 2 squared and add them, you then find the square root and that should equal 10, if not its not a triangle.
