Answer:

Step-by-step explanation:

We can check with the Pythagorean Theorem.

a^2 + b^2 = c^2

a and b are always the smaller sides, the legs

c is the longer side, the hypotenuse

3^2 + 3^2 > 6^2

9 + 9 > 36

18 < 36

18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.
