Mirrors and Angles Investigation
In this practical activity, from the Royal Institution, students use paired mirrors to investigate repeated reflections and the symmetrical properties of certain polygons. Based on observations made about these symmetries, students then look at how the mirrors and reflections allow them to deduce the angles in various shapes, as well as the different polygons they can make using cardboard triangles and mirrors. Teachers' notes, with detailed information, are also provided to accompany the presentation for students.
