    two polygons are similar when they have all the angles same...so did you check all the angles?

    you can draw a parallel line to the horizontal line and if you will check their sin of the angle they will be different

    it don't matter with the size if its the same shape then its similar no matter what

    In triangles, AA (all angles equal) will imply similarity of triangles. The same rule (all angles equal) does not guarantee similarity of polygons of 4 or more sides, see counter example below: |dw:1433249090711:dw|

    To guarantee similarity of polygons, we must have 1. all angles equal, and 2. at least n-1 \(corresponding\) sides proportional, n is the number of sides of the polygon.

    It's not done! The question is flawed!

    |dw:1433249544160:dw| is sufficient to prove that the two polygons are similar, because the two squares are similar, and the two triangles are also similar. @joeylup

    The addition of the two sides \(contradicts\) the similarity. You will find that it is impossible to draw the two polygon with the given dimension including the sides 10 and 11 without violating some of the other information.|dw:1433249815704:dw|

    I.e. if all the dimensions are as prescribed, the two acute angles cannot be equal. This is the flaw of the question.

    The expected answer of the question is \(probably\) "not similar", but you should talk to your teacher about it.
