Geometry definition of similarity
WebMar 4, 2016 · Yes indeed. Every circle is similar. You can always scale one of them to match the other. Actually, this is the definition of similarity. In case of triangles, this definition yields the result that the sides are proportional. "The sides of one triangle are proportional to the other" is not the actual definition of similarity. In Euclidean geometry, two objects are similar if they have the same shape, or if one has the same shape as the mirror image of the other. More precisely, one can be obtained from the other by uniformly scaling (enlarging or reducing), possibly with additional translation, rotation and reflection. This means that … See more Two triangles, △ABC and △A′B′C′ are similar if and only if corresponding angles have the same measure: this implies that they are similar if and only if the lengths of corresponding sides are proportional. It can be shown that two … See more Several types of curves have the property that all examples of that type are similar to each other. These include: • Lines (any two lines are even congruent) • Line segments • Circles See more If a similarity has exactly one invariant point: a point that the similarity keeps unchanged, then this only point is called "center" of the similarity. On the first image below the title, on the left, one or another similarity shrinks a regular polygon See more The concept of similarity extends to polygons with more than three sides. Given any two similar polygons, corresponding sides taken in the same sequence (even if clockwise for one … See more A similarity (also called a similarity transformation or similitude) of a Euclidean space is a bijection f from the space onto itself that multiplies all distances by the same positive See more The ratio between the areas of similar figures is equal to the square of the ratio of corresponding lengths of those figures (for example, when the … See more In topology, a metric space can be constructed by defining a similarity instead of a distance. The similarity is a function such that its value is greater when two points are closer … See more
