IM Geometry: Unit 2 - Congruence
- Topic:
- Algebra, Angles, Congruence, Geometry, Parallelogram, Quadrilaterals
In this unit, students begin by reasoning about the relationships between congruent parts of figures, and congruent figures. They use transformations as tools for reasoning and generalizing.
