samaväärsuste
Samaväärsuste, often translated as equivalences, refers to a fundamental concept in mathematics and logic concerning relationships that share certain properties. These properties are reflexivity, symmetry, and transitivity. A relation is reflexive if every element is related to itself. It is symmetric if whenever element A is related to element B, then element B is also related to element A. Finally, a relation is transitive if whenever element A is related to element B and element B is related to element C, then element A is also related to element C.
When a relation satisfies all three of these properties, it is called an equivalence relation. Equivalence
Examples of equivalence relations are abundant. Congruence of geometric figures (e.g., two triangles are congruent) is
