The only shape that is symmetric about a point are a circle, sphere and their multi-dimensional counterparts. There are many more functions that are symmetric about the axes or specific lines.
there are many symmetric numbers. 111, 121, 454, 252, 999, 545 etc
symmetric about the y-axis symmetric about the x-axis symmetric about the line y=x symmetric about the line y+x=0
