Axisymmetric and axisymmetric graphics are two related concepts. Axisymmetry means that two geometric figures are symmetrical about a straight line if the line segment connecting their corresponding points is vertically bisected by the straight line. In other words, these two figures are symmetrical. This must be a straight line called the axis of symmetry.

Axisymmetric figure means that if the symmetrical figure of a figure about a straight line coincides with itself, such a figure is called axisymmetric figure. This straight line is called the symmetry axis of this figure.
