The Similarity Ratio Can Be Used Not Only for Side Lengths But Also for Heightsĭepending on the similarity ratio, the side lengths will change. If the side length ratio is 1:3, the similarity ratio of the two triangles is 1:3. For example, in the following case, the similarity ratio is 1:3. In similar figures, the ratios of the corresponding side lengths are the same. Similarity ratios should be understood as ratios of the side lengths. The calculation used is the similarity ratio. In similarity figures, it is important not only to prove that the figures are similar to each other but also to use the similarity to calculate the side lengths. Relationship Between Similarity Ratios and Side Lengths After that, you can use the similarity theorem to prove that the triangles are similar. Try to find triangles that are similar by looking for two sets of the same angles. Therefore, in similarity problems, we first consider Angle – Angle (AA). It is rare to use Side – Side – Side (SSS) or Side – Angle – Side (SAS) to prove the similarity of triangles. Note that in most cases, we use Angle – Angle (AA) to prove the similarity of figures. If two pairs of angles are equal, then each shape is similar. If the side length ratios of the two pairs are equal and the angle between the sides is the same, the two figures are similar. Side – Angle – Side (SAS) Similarity Theorem If the ratios of three pairs of sides are all equal, they are similar. Side – Side – Side (SSS) Similarity Theorem

Since the figures are enlarged or reduced, the side length ratio of each similar figure is the same. The Corresponding Side Length Ratios Are Equal Also, similarity has the following properties. Understand that a similar shape is one in which the side lengths are larger or smaller. On the other hand, figures that are the same in shape but different in size are called similarity.įor example, the following figures have a similarity relationship. Congruence refers to shapes that are exactly the same. There is a difference between congruence and similarity. What Is The Difference Between Congruence and Similarity: Properties of Similarity
