About this lesson
This is another video in the Year 9 Mathematics series relating to Geometry. This video looks at Enlargement and Similar Figures. Having already looked at what congruence is, it makes sense to look at the idea of similar figures. These are figures which have the same size angles but every side length has been multiplied by the same scale factor. I use a number of worked examples to support the theory which is explained in an easy to understand way.
