Collapsing Compass Equivalent to Rigid Compass

This example demonstrates how to use a collapsing compass (a compass that can only draw circles with a fixed radius) to construct geometric figures, equivalent to a rigid compass (a compass that can maintain a fixed distance while moving). The core mathematical concepts include geometric constructions involving circles and line segments. Using GeoGebra commands Segment and Circle, the example shows how to draw a line segment between points A and B, and a circle with point A as the center and point B as the radius. Suitable for middle school and above students learning geometric constructions.
