Question

what is a dimension? Does point have any direction? If it has why? if it doesn't have why?

Answer 1

Dimension means area

Answer 2

Dimensions are the directions in which any physical quantity would operate. There are 3 dimensions(for normal purpose). These include left-right, up-down, backward-forward. A point 's direction is considered arbitrary . Thus is because a point in space is considered a stationary particle and a stationary particle does not have any direction. If you assumvit to have any direction than you are saying your car parjed in the parking lot and the car is climbing a tree, since this cannot happen so we conclude that a point does not have any direction
