Ms Marshall 3rd Year Maths Translations Part 3 Axial Symmetry Ms Marshall 3rd Year Maths

Ms Marshall 3rd Year Maths Axial Symmemtry Axial symmetry is a reflection in a line. It involves reflecting points through a line. It is the mirror image of the object. Therefore the figure will flip over. The mirror line becomes a line of symmetry. Ms Marshall 3rd Year Maths
