Congruence Postulates by Fred Blattner

This example illustrates the congruence postulates for triangles, including SSS, SAS, ASA, and AAS. By adjusting the lengths of sides and angles, students can visually understand these postulates. The construction uses basic objects such as points, line segments, angle measurements, and congruence transformations. Suitable for middle and high school students learning geometric constructions and congruence of triangles.
