Set Operations Illustrated by Venn Diagram

① This example demonstrates set operations such as union, intersection, and complement using a Venn Diagram, where overlapping circular regions visually represent relationships between sets. ② Core mathematical concepts include set theory fundamentals, including intersection, union, difference, and complement, along with geometric representation of logical relations. ③ Construction details: The GeoGebra construction uses commands like Polygon, Circle, Intersect, and CircleArc, creating multiple circles (Circle1 through Circle6) and quadrilaterals (Quad1, Quad2, quad3). Intersection points (E, F, G, H, I, J) and circular arcs (ArcEJI, ArcEIJ, ArcGIJ, ArcGJI) partition the regions, with distinct colors or shading indicating different set operation results. ④ Suitable for middle school, high school, or introductory university courses in discrete mathematics or set theory, and useful for teachers creating interactive lessons to help students grasp abstract set operations through visual intuition.
