Let
=
and
=
. Let θ be the angle between the vectors
and
.






We can construct
= (
-
) as shown in figure.



OSPQ is parallelogram and PQ = | (
-
) |


As per the given condition , |
| = |
| = | (
-
) | , all the sides of ΔOPQ are same .




Hence θ = 60o = ( π / 3 ) rad
Hence angle between
and
is 60o or ( π / 3 ) rad
