Which do you think is the bigger difference between the two squares? (Figure 2) Known; Point p outside the circle is the three secant lines of the circle. The left one intersects with point A at point D, the right one intersects with point B at point E, and the middle one intersects with point C (between D, E, PA, PB and PC).
