Common Core Math - HS Geometry
Lesson Plan
Define transformations formally
Goals / Objectives
State the formal geometric definition of a translation in terms of direction, distance, and parallel line segments
State the formal geometric definition of a reflection in terms of a line of reflection and perpendicular bisectors
State the formal geometric definition of a rotation in terms of a center point, angle, and circular arcs
Explain how each definition uses the precise geometric terms from HSG.CO.A.1 (angles, circles, perpendicular lines, parallel lines, line segments)
Use formal definitions to verify whether a given mapping is or is not a specific type of transformation
Standards
HSG.CO.A.4
HSG.CO.A.4: Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments.
