Grade 9 Math | Proving Triangle Congruence Using Two Column Proof Second Term (Term 2) Week 5

What is a two column proof? What are the parts of two column proof? How to construct congruence proof of two triangles are congruent? The learning competency of this lesson is Construct congruence proofs involving triangles or corresponding parts of triangles using a two-column proof. The learning objectives are identify the components of a two-column proof, including statements and reasons; Recall the triangle congruence postulates and theorems (SSS, SAS, ASA, AAS, LL, HA, LA and HL). Apply properties, definitions, and theorems to complete congruence proofs involving triangles; Construct two-column proofs to justify the congruence of triangles. Demonstrate accuracy, organization, and logical thinking when constructing two-column proofs. This video lesson discussed and presents construction of two column proof to prove triangle congruence. It include activity and formative test to master the lesson about constructing two column proof. #Term2 #Secondterm #Week5 #Grade9mathematics #Math9 #Twocolumnproof #provingtrianglecongruenceusingtwocolumnproof #Partsoftwocolumnproof #RevisedKto10
