WebNow that we have formally defined set properties in terms of our logical operations, we can now use our logical equivalences to formally prove statements about sets. We'll start with … WebLogical equivalence is the idea that more than one expression can have the same meaning, but have a different form (often a form that helps make the meaning more clear). Imagine …
WebAs with logical equivalence and logical entailment, we can use the truth table method to determine logical consistency. The following truth table shows all truth assignments for the propositional constants in the examples just mentioned. WebLogical equivalence Definition: a pair of sentences are logically equivalent if and only if it is not possible for one of the sentences to be true while the other sentence is false. A pair of sentences may turn out true under exactly the same circumstances.

For a given set of triangles, the relation of ‘is similar to (~)’ and ‘is congruent to (≅)’ shows equivalence. For a given set of integers, the relation of ‘congruence modulo n ...
