Invariant is a property, held by a class of mathematical objects, which remains unchanged when transformation.
Transformation: is a function who maps to itself, in Euclidean geometry, move every point in the same direction or a constant vector for every point as shifting the origin of the coordinate system. The syetem can be rotate (sniping)
