The magnitude of the cross product of two vectors is equal to dot product of the same two vectors. What is the angle between two vectors?

Given,

Magitude of cross product is equak to the dot product of two vectors. 

i.e., 

    space space open vertical bar straight A with rightwards arrow on top cross times straight B with rightwards arrow on top close vertical bar space equals space open vertical bar straight A with rightwards arrow on top times straight B with rightwards arrow on top close vertical bar
