Venn Diagram Logic with Two Sets by Elen

① This example demonstrates the logic of Venn diagrams using two intersecting circles, visually showing the intersection, union, and exclusive parts of two sets. ② The core mathematical concepts involve set theory operations (intersection, union) and logical reasoning, combined with geometric elements such as circles, arcs, and polygons to partition regions. ③ Construction highlights: using GeoGebra commands like Point, Circle, Intersect to create the circles and their intersection points, CircleArc and CircumcircleArc to define curved boundaries, and Polygon to fill distinct regions, with text objects (text1, text2) labeling the sets. ④ Suitable for middle school or introductory logic courses, this interactive model helps students grasp set operations and Venn diagram construction, and serves as a useful teaching tool for educators.
