This film shows how a set square can be used to reflect points and figures along axes and points. Clear examples explain why the scales on a set square are inverse and how they can be used along with the corresponding auxiliary line to simply create the mirror image of objects. Rotational symmetry is also explained and practical examples are presented to demonstrate the relationship between the number of symmetrical axes and the stability of naturally occurring objects.
