Is it possible to draw a triangle with numbers 5,6,11
Tatiana [17]

Answer:

No

Step-by-step explanation:

Let's use the Pythagorean Theorem. For those of you that don't know, it is a^2 + b^2 = c^2\\.  

11 is the bigger side in this case, so our formula would go like this: 5^2 + 6^2 = 11^2\\.

We now calculate to see if this is true.

25 + 36 \neq 121

Therefore, the answer is wrong.
