The '''Y-Δ transform''' is known by a variety of other names, mostly based upon the two shapes involved, listed in either order. The '''Y''', spelled out as '''wye''', can also be called '''T''' or '''star'''; the '''Δ''', spelled out as '''delta''', can also be called '''triangle''', '''[[Pi (letter)|Π]]''' (spelled out as '''pi'''), or '''mesh'''. Thus, common names for the transformation include '''wye-delta''' or '''delta-wye''', '''star-delta''', '''star-mesh''', or '''T-Π'''. {{clear}}
