Properties & definitions of transformations

# Defining transformations

## Problem

Tony tried to define a translation.
• Point A maps to point A, prime.
• Every point P maps to point P, prime such that P, P, prime, with, \overrightarrow, on top is parallel to A, A, prime, with, \overrightarrow, on top and points in the same direction as A, A, prime, with, \overrightarrow, on top.
What mistake did Tony make in his definition of a translation?
