Similarity involving Length
In this section you will learn what Similarity is. Figures are similar when their corresponding angles are equal in size (the same) and corresponding sides are in proportion. That means that if one side of a figure is twice as big as the corresponding side in another figure, all sides will have to be twice as big in order for them to be Similar Figures. The Scale Factor in the previous example would be two. The bigger figure is twice as large as the smaller figure, or the smaller figure is half the size of the bigger figure (twice as small). If you want to understand Similarity I encourage you to look at all videos. Each video contains an example question slightly different than than the example question in the other videos. In other words, you will learn something new and important about maths and Similarity in each video. Let me know on the forum of this site if you still do not understand similarity and I will help you! Before you start, are the two telephonecabins on the picture similar?
