idea in geometry From Wikipedia, the free encyclopedia
Similarity is an idea in geometry. It means that two polygons, line segments, or other figures can become the same via resizing. Similar objects do not need to have the same size. Two shapes are similar if their angles have the same measure and their sides are proportional. Two circles, squares, or line segments are always similar. If figure is similar to figure , then we write .[1][2][3]
Similarity is very similar to congruence. Congruent shapes have the same sides and angles. Because of that, two shapes are congruent to each other if one can become another through rotating, reflecting or moving only.[2] In fact, all shapes that are congruent to each other are also similar, but not vice versa.
