The document discusses various vocabulary terms related to geometry and symmetry such as symmetry, line of symmetry, size, part, whole, congruence, and equal length. It provides definitions and examples for each term to help explain the meaning. For example, it defines symmetry as a correspondence in size, form, and arrangement of parts on opposite sides of a plane, line, or point. It also shows examples of symmetrical stained glass windows and instruments.
