Segment Addition Postulate Demonstration by Alexis Gelinas

This GeoGebra worksheet demonstrates the Segment Addition Postulate: when point C lies on segment AB, the distance AC plus CB equals AB. Key mathematical concepts include the segment addition postulate, distance calculation, and the positional relationship between points and line segments. Construction details: Use the Segment command to draw segments AB, AC, and BC; use the Point command to create draggable point C on the segment; use the Distance command to measure distanceAB, distanceAC, and distanceCB; display the numerical relationships using text objects. Ideal for middle school geometry introduction or as a teaching tool for demonstrating basic segment properties.
