what is the definition of similarity
Answers
Answer:
the state or fact of being similar.
Step-by-step explanation:
A similarity is a sameness or alikeness. When you are comparing two things — physical objects, ideas, or experiences — you often look at their similarities and their differences. Difference is the opposite of similarity. Both squares and rectangles have four sides, that is a similarity between them.
In Euclidean geometry, two objects are similar if they have the same shape, or one has the same shape as the mirror image of the other. More precisely, one can be obtained from the other by uniformly scaling, possibly with additional translation, rotation and reflection.
