This PowerPoint offers some general maths revision to begin with before explaining what angle/ line bisectors are. The Power Point is made as interactive as possible to allow students to work with the teacher to complete each bisector example. Once students feel more confident, accurately drawing shapes to measure (e.g. triangles) can be then be tackled.
I hope this PowerPoint reduces the need to print and offers a good source of revision. Learning aims are also included so students can measure their level of understanding and success in class. A lesson students have enjoyed.
