CircleProbability & StatisticsGeometric Construction
This example demonstrates how to create a circle graph by dragging points. It involves core math concepts such as circles, sectors, and percentages. Using GeoGebra commands like Circle and CircleSector, it visually represents data distribution. Suitable for middle school and above students to learn data statistics and graphical representation.
