Step through the relationships of complementary, supplementary, vertically opposite and angles at a point with this animated teaching presentation.   Each relationship is visualised and animated to display degrees and angles as measurements of turn.   The four relationships included in this teaching presentation are:

1. Complementary Angles
2. Supplementary Angles
3. Vertically Opposite Angles
4. Angles at a Point.

  Use this presentation as a whole-class warm-up or mini-lesson before having students complete individual work on angle relationships.
