Description

Overview:
This lesson unit is intended to help you assess how students reason about geometry and, in particular, how well they are able to: use facts about the angle sum and exterior angles of triangles to calculate missing angles; apply angle theorems to parallel lines cut by a transversal; interpret geometrical diagrams using mathematical properties to identify similarity of triangles.

This is a lesson/assessment unit. There are many resources for the teacher to aid in the lesson. There are student handouts, assessments, assessment revisited, ppt, explorations for students, suggested questions and prompts for common issues. It is addressing CCSS 8.G.5 to use properties of triangles to identify similar triangles.
