drawing sigma/pi bonds

How do you determine when/ where to draw sigma and pi bonds?

All bonds contain a sigma bond and double and triple bonds contain a single bond each and 1 & 2 pi bonds respectively. The sigma bond is formed by the head-on overlap of two sp orbitals while the pi bonds are formed by the side-on overlap of the p unhybridized orbitals.

As for drawing (if you mean as in a lewis structure), you would just draw single, double, or triple bonds. To draw the actual bond, as the replier above stated, sigma bonds would be the head to head overlap of the s or p orbitals, whereas pi bonds would be the side to side overlap of p bonds.

we would just label the single, double, or triple bonds as sigma or pi bonds if asked right

All single bonds would be labeled as sigma bonds, double bonds would have one sigma bond and one pi bond, and triple bonds would have one sigma bond and two pi bonds.

What is the difference between a sigma bond and a pi bond?

For the difference between sigma and pi bonds, they are different in length and strength sigma bonds are longer than pi bonds and are weaker. Pi bonds are stronger. Also, in sigma bonds, the atoms involved can rotate. In pi bonds, they cannot.
