Venn Diagram: Visualizing Set Operations

① This example demonstrates a Venn Diagram constructed with two intersecting circles to visualize basic set operations such as intersection, union, and complement. ② Core mathematical concepts include set theory, set operations, frequency distribution, equilateral triangles, and connections to calculus and arithmetic operations. ③ Construction details: Using GeoGebra commands Point, Circle, Intersect, and CircleArc, the diagram creates two circles (c, d) with intersection points (C, D), and uses text objects (text1 to text5) to label regions; auxiliary objects include points A, B, and arcs (e, f, g, h) to partition the sets. ④ Suitable for middle school through university mathematics education, particularly for introducing set theory, probability events, and interactive geometry-based learning, and for teachers creating dynamic visual aids.
