Reflections

Curated and Reviewed by Lesson Planet

Take some time to reflect on graphing. Learners count a point's distance from the line of reflection to create reflections of geometric figures. Given the rules for four basic lines of reflections, pupils determine the points to create the image of a figure. Scholars practice both methods of reflection during the instruction and afterward with the worksheet.
