Lesson Plan

Select appropriate congruence criteria (ASA, SAS, SSS, AAS) to prove triangles congruent in multi-step problems

Select appropriate similarity criteria (AA, SAS similarity, SSS similarity) to prove triangles similar in multi-step problems

Use triangle congruence to prove relationships in geometric figures such as properties of quadrilaterals, medians, and angle bisectors

Use triangle similarity to solve problems involving indirect measurement, proportional relationships, and geometric means

Combine congruence and similarity criteria strategically to solve complex geometric problems

Justify each step in a geometric proof using previously established theorems and definitions
