How do you determine the difference between sigma and pi bonds?

If it is a single bond, it is a sigma bond, any additional bonds (the second bond within a double bond or the second and third bonds in a triple bond) are pi bonds. Sigma bonds occur end to end while pi bonds are side to side; sigma bonds allow atomic rotation and are therefore stronger than pi bonds, which do not allow for atomic rotation
