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 Side – Angle – Side (SAS) Similarity Theorem.Side – Side – Side (SSS) Similarity Theorem.Here are the similarity conditions for triangles. When do triangles have similarities? There are three similarity theorems for triangles in total. Three Conditions for Triangles to Be Similar In the same way, remember to use a special symbol for similarity. In this case, △ABC and △EDF are similar.įor congruence, we use the ≅ symbol. In addition, the symbol ∼ is used in similarity. In the case of similarity, the angles are always the same, and the only difference is the side lengths. If the angles are different, the shape of the figure will change. On the other hand, for angles, they are the same for all pairs of angles. The Sizes of the Corresponding Angles Are Equalįor the side lengths, all ratios are equal for similar figures, as mentioned above. If the figures are similar and the side ratio is known, the other side lengths can be calculated. For example, if one side is doubled in length, all the other sides will also be doubled. 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.
