Tick Boxes, Union and Intersection by Jason Murphy

This example demonstrates the geometric and set-theoretic concepts of Tick Boxes, Union, and Intersection using GeoGebra. It illustrates how to represent sets through geometric shapes and perform operations like union and intersection. Key mathematical concepts include set operations, geometric representation, and coordinate geometry. The construction involves creating points A, B, C, defining functions f, g, h, and parameters a, b to visualize the intersection of geometric shapes. Suitable for middle school students learning set theory and geometry, or for educational demonstrations.
