Where are they?
please explain the work
Well.. what do you think?
Are they similar?
well no i dont think they are similar
two polygons are similar when they have all the angles same...so did you check all the angles?
yea but how do i do the work i need help
you can draw a parallel line to the horizontal line and if you will check their sin of the angle they will be different
@joeylup they are similar
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.
Ok guys i get it now thx for the help @mathmate
It's not done! The question is flawed!
yea i know but i know what to do
|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.
