Re: identifying pi & sigma bonds
Sigma bonds are in single bonds, double bonds, and triple bonds; it's kind of like the first bond. Pi bonds are in double bonds and triple bonds; it's kind of like the subsequent bonds to pi bonds. Single bonds have one sigma bond, double bonds have one sigma bond and one pi bond, and triple bonds have one sigma bond and two pi bonds.

Re: identifying pi & sigma bonds
All single covalent bonds are sigma bonds. When it comes to double and triple bonds, pi bonds are introduced,including the one sigma bond, with a double bond having one pi bond + one sigma bond and a triple bond having two pi bonds + one sigma bond. Also note that sigma bonds form when two 1s orbitals merge together (which is the case for H2), when the two 2pz-orbitals merge together, and when a 1s orbital and a 2pz orbital merge together. A pi bond forms when two 2p-orbitals merge together.
