Reflections & Rotations Transformations Reflections & Rotations Essential Questions: How can you change a figures position without changing its size or shape? How can you change a figures size without changing its shape? How can you represent a transformation in the coordinate plane? How do you recognize congruence and similarity mappings?

Reflections Goal: To find reflection images of figures. Essential Understanding: When you reflect a figure across a line of reflection, the line of reflection is the perpendicular bisector of each segment connecting a point and its image.

Reflections Goal: To find reflection images of figures. Essential Understanding: When you reflect a figure across a line of reflection, the line of reflection is the perpendicular bisector of each segment connecting a point and its image.
