Step-by-step explanation:
1. Translations are a function of distance and direction. It is mathematically represented by,
f( distance, displacement )
It is a form rigid motion.
2. Translation is one of the four form of rigid motions. In translation, every point on the object move by the same and equal amount in the same direction. This is nothing but a rigid motion as in rigid motion the objects moves to a different place without changing its shape and size.
