Hope this helps u

Explanation:

When the vector length is turned through the angle theta, it forms an arc.

An isosceles triangle will be formed when you join both the heads of the vector. Based on it, the position of the vector head is determined.

The change in position of the vector head is as follows

Theta*l (the arc length =radius length *angle created)

When the vector length rotates by angle about its tail, the head traces an arc. If you join the end points of the arc, you will observe an isosceles triangle of equal sides and angle between them . ... This is the magnitude of the displacement of the head of given vector of length , moving about its tail through angle .
