What is the condition of two vectors to be parallel?

if A= A1i+A2j+A3k and B=B1i+B2j+B3k then what is the condition that the two vectors are parallel..

2. Relevant equations

A*B=AB sin(theeta)

3. The attempt at a solution

by cross product i find the condition

A1/B1=A2/B2=A3/B3 .... under which determinant becomes equal to to 0. which is the condition for parallel..theeta = 0 so sin 0 = 0 ... kindly confirm is it write or wrong.
