What you'll learn
- 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
