Understanding Triangle Congruence Transformations

This video tutorial explains congruence using rigid motions such as reflections, rotations, and translations. It aligns with the Common Core State Standards for Mathematics, focusing on eighth-grade and high school geometry. The tutorial uses GeoGebra to demonstrate how to transform one triangle to match another by labeling, translating, and rotating. The process involves setting up transformations, checking orientation, and using tools in GeoGebra to achieve congruence.
