    I'm pretty sure I answered a question very similar to this. We have to use Pythagoras Theorem here to verify the shape. |dw:1438649421867:dw|

    If it is a square, then the other side should also be 17. With Pythagoras Theorem, you get this: \[17^2+17^2=18.79^2\] \[289+289\neq353\]

    Hence it is not a square. Do you understand?
