This educational diagram explains symmetry in graphs, showing y-axis symmetry (where (x, y) and (-x, y) are points), x-axis symmetry (where (x, y) and (x, -y) are points), and origin symmetry (where (x, y) and (-x, -y) are points), with visual examples for each type.

A diagram illustrating three types of symmetry in graphs: y-axis symmetry, x-axis symmetry, and origin symmetry, with examples and definitions for each.
