MATH.7:2 - Problem

Changing the names or coordinates of elements leaves the receiving operations undecided. Reusing the familiar operation on the new labels can produce a different result. Even when one operation survives unchanged, another quantity or relation may require a different formula.

The task is to construct the receiving structure, establish what it preserves, and use that preservation to calculate or solve a problem. If the receiver already requires particular operations, the transported construction must be compared with them.
