About this lesson
This is another video in the Year 11 General Maths (Units 1 and 2) VCE course relating to measurement, scale and similarity. This video looks at the idea of similarity in triangles. We already know that similar figures have the side lengths all in the same ratio, but what if they don't give me all the side lengths? Well, for triangles we know that we have three rules we can use to check for similarity when we don't know all the sides. In this video I look at the AA, SSS and SAS rules. I look at how they work with some great worked examples! The theory is all explained in an easy to understand way designed to help you smash maths.
