Common Core Math - HS Geometry
Lesson Plan
Define geometric terms precisely
Goals / Objectives
State precise definitions for angle, circle, perpendicular line, parallel line, and line segment
Explain how these definitions build on the undefined notions of point, line, distance along a line, and distance around a circular arc
Distinguish between defined terms (those built from undefined concepts) and undefined terms (accepted without definition)
Use precise definitions to identify whether given examples satisfy the definition of each term
Recognize the importance of precision in mathematical definitions and how it differs from informal everyday language
Standards

HSG.CO.A.1: Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc.
