Venn Diagram Set Operations Self-Test

This example demonstrates and practices set operations using Venn diagrams. The core mathematical concept is set theory including intersection, union, and complement operations with visual representation. It uses GeoGebra commands: Polygon to draw the three circular regions of the Venn diagram, If for interactive judgment logic, Segment for auxiliary lines, Element to extract specific elements from sets, and Length to calculate set cardinalities. The file contains text objects (text1-text5) for displaying questions and feedback, and a startover button for repeated practice. Suitable for high school mathematics set and logic units, or as an introductory practice tool for discrete mathematics in universities.
