WebMay 4, 2011 · Sorted by: 1. You compute the center of gravity of your polygon. You translate it to the origin so that your center of gravity has (0,0) as coordinate. Then for each vertex of coordinate (i, j) you check that there is a vertex that has coordinates (-i, -j). This will prove that your polygon is symmetric indeed. WebA line of symmetry is a line that you can draw across a shape and divide it into two mirror-images. That is to say, each half of the shape is the same, but looks like its been flipped from the other. You can also think of a line of symmetry as a line that you can draw, that when you fold the shape over the line both edges would line up exactly ...
