Basic Geometric Definitions → Writing Congruence Proofs
This learning path guides middle school students from basic geometric definitions to proving triangles congruent using SSS, SAS, ASA, AAS, and HL criteria, and applying CPCTC. It covers prerequisite knowledge about angles and triangles, then systematically introduces each congruence criterion with practice in writing two-column proofs.
