Reflection: Grappling with Complexity Analyzing the Symmetry of a Polygon - Section 3: Analyzing Shapes


In today's lesson we work carefully to build a path to rigorous mathematical proof as we analyze the Symmetry of Polygons. I discuss my rationale for this in a Reflection Video

Analyzing the Symmetry of a Polygon

Unit 3: Congruence and Rigid Motions
Lesson 14 of 17

Objective: SWBAT describe the transformations that carry a polygon onto itself. Students will understand the meaning of symmetry in terms of rigid motions.

Big Idea: Students use the symmetry of a polygon to deduce its properties while continuing to develop their ability to use transformations. Now, just where does that line of symmetry have to be?
