GeoGebra Line Segment Copy: Geometric Construction Basics

This example demonstrates how to copy a line segment in GeoGebra. The core mathematical concept is segment equality and triangle congruence criteria. Construction steps: 1) Use Segment command to create the original segment AB; 2) Draw a circle centered at A with radius AB; 3) Draw another circle centered at B with the same radius; 4) Use Intersect command to find intersection points C of the two circles; 5) Connect BC to form a new segment congruent to AB. Key GeoGebra commands used: Segment, Ray, Point, Circle, and Intersect. This is suitable for middle school math teachers demonstrating geometric construction methods and students practicing basic GeoGebra operations.
