SAS Congruence Postulate

This example illustrates the SAS Congruence Postulate, which states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent. Key mathematical concepts include triangle congruence, vectors, distance, and angles. It is constructed using GeoGebra commands such as Polygon, Vector, Distance, and Angle. Suitable for middle school and above students to learn geometric construction and triangle congruence.
