END OF UNIT COMPETENCIES WITH LANGUAGE EXPECTATIONS

By the end of Unit 7, students will be able to: ● identify congruent angles and sides between two triangles ● prove two triangles are congruent using correct math vocabulary such as: ○

congruent, equal, corresponding angles/sides/parts, ASA, SAS, AAS, SSS, CPCTC

● identify triangle congruence criteria ● explain how a sequence of rigid motions can be used to justify triangle congruence using correct math vocabulary such as: ○ coincide, corresponding angles/sides/parts, refection, translation, rotation, ● construct various geometric objects ● describe a sequence of transformations that would be used to get one shape onto another SCAFFOLDING IN ACTION
