No. Power in the USA is either single phase or 3-phase. You do not have 3-phase at home.

Transformer that produces 240 volts has a center tap. Each hot has 120v to the center tap (neutral) and 240 volts to each other. A better term is 'split phase'. Still it is single phase power.

The word 'phase' has two different meanings that get crossed up with alternating current. The two meanings have to do with phase shift and frequency. wiki explains it better than I will here.
