How do I get "coords" of multiple polygons with the same "tag"

[smh]

I have a canvas where I draw multiple polygons which have the same "tag". I re-scale the canvas and would like to get the coordinate of the polygons. WHen I use the "coords" method, I get the coordinates for one of the instances (as described by the documentation).

I was wondering is there a way to get "coords" method to get the other polygons also.

I do not have code for this since I do not know how to do it.

Thanks in advace
