Question

Can the sides of a triangle have lengths 2,6, 9?

Answer 1

Answer:

No

Step-by-step explanation:

Using the Pythagorean theorem,  a squared + b squared = c squared, where c is the hypotenuse. 2 squared is 4, 6 squared is 36. 4+36 is 40, but 9's square is 81. This means that it can't be a triangle.

Hope this helps :)
