currently if i forget i figure these out using the right hand rule, but how do you get each equation visa versa using vector algebra

i started with w = rxv

how do you derive that v = wxr

i got up to this

w = rxv

w= -(vxr)

rxw = -rx(vxr)

rxw = v(r.r) - r(r.v)

rxw= v -r(r.v)

but can u assume r.v are perpendicular?

is this the right approach? and you even relate the 2 equations this way??
