Picture Perfect Geometry
This lesson is one part of a larger unit plan that covers all the properties of triangles and several other theorems. It has proofs, real world problems, constructions, a unit project, assessments, and more. In Lesson 3, “Picture Perfect Geometry”. students review Geometry vocabulary by producing a booklet of terms with associated real world pictures. The entire unit plan can be found here. This lesson is the beginning of the Unit Project, but could be adapted to use independently.
