Identifying rotational symmetry is a new topic in P7.  If you have tracing paper or even greaseproof paper, it would be quite useful to trace the shapes, cut them out and then rotate them on the original shape but this is not essential.  Watch the two videos and then complete the two worksheets.  The answers are provided underneath.  If Circles want a real challenge, they could also watch the Corbettmaths video on rotating shapes and have a go at the worksheet.  Tracing paper is definitely advised!
