What is the direction of a vector?

The direction of a vector is the orientation of the vector, that is, the angle it makes with the x-axis. A vector is drawn by a line with an arrow on the top and a fixed point at the other end. The direction in which the arrowhead of the vector is directed gives the direction of the vector.

How are vectors denoted?

When a vector is represented graphically, its magnitude is represented by the length of an arrow and its direction is represented by the direction of the arrow.
