Whether you are venturing into Geometry for first time or you are prepping for more advanced levels of Trigonometry, Congruent Triangles provides a wide range of concepts and levels through which to practice, perfect and challenge your skill set. Begin with learning the language in our topic Notation for Congruent Parts or diving into Triangle Congruence Theorem (HL), there are areas of challenge presented with each lesson. Identify key components to contrast between SAS Triangle Congruence, AAS Triangle Congruence and ASA Triangle Congruence. From Overlapping Triangles to CPCTC, you will attain profiency from the basics to more sophisticated geometric techniques.
