About this lesson
This is another video in the Year 9 series relating to Geometry. In this video I take a look at how we can prove triangles are similar using one of four rules. Using these rules we can write concrete statement to "prove" that triangles are similar. I have seen too many of these types of questions in exams to ignore them ... hence the video. I also look at how we can find missing side lengths of triangles using similarity. I have seen questions which use this concept all the way to Year 12 VCE Mathematical Methods! So, hopefully the video will be a good one for you.
