No trinity analogy is perfect but this one is a good one for showing that there is only one God that portrays himself in three persons. It is a heart with three “God shaped holes”, a circle to show God the father because He is eternal - No beginning and no end, a square to represent Jesus the 3 dimensional God, and a triangle to present the Holy Spirit who completes the trinity. You then show three pieces that fit the holes. Then you present a secret piece that completely fits all three holes One piece that fits all the holes - On God in three persons!
