Fixing Angles in Polygons

I created an activity introducing my class to similar triangles. When they started the activity they were able to change the angles of the polygons, making the sets of triangles not similar. How can I fix the angle measure in the polygon so they can not change them? I don't mind if the lengths change so long as the angle measures stay the same (in fact this would be preferable).
