Compass and Straightedge Construction: Copying an Angle
2020-12-24 08:23
This GeoGebra applet demonstrates the classic compass and straightedge construction of copying a given angle. The construction involves drawing circles, finding intersections, creating segments, and drawing circular arcs. It illustrates the application of the Side-Side-Side (SSS) congruence theorem in Euclidean geometry. Ideal for middle school geometry teaching and learning basic geometric constr
