This example investigates the relationships between the sides, angles, and diagonals of a square. By measuring different segments, you can discover which segments are congruent. The construction uses GeoGebra commands such as Polygon, Segment, Intersect, Distance, and Angle. Suitable for middle school and above students to learn geometric construction.
