What We Did Today:
Students started Problem 1.1, Butterfly Symmetry: Line Reflections. Students discovered relationship between a line of reflection and the line segments drawn from an original vertex to its reflection vertex. Students used these generalized relationships to draw their own reflections. Notes and vocabulary words that were discussed are available at http://norupstein.weebly.com/math-8-plus-blog
What does it mean to say that a figure has flip or reflectional symmetry? How is each point related to its image under transformation by reflection in a line?
