This video is another in the series relating to Geometry for the Year 9 course. The concepts held within are so important as they come up time and time again. Looking at Quadrilaterals and other polygons, I show you how to find the interior and exterior angles of polygons, and how some of the more interesting ones work. Do you want to know about their properties? Well, I have a section on that too. Want to have some humour and laugh whilst you're learning, well I can do that too.
