I can use the properties of translations, rotations, and reflections on line segments, angles, parallel lines or geometric figures. I can show and explain two figures are congruent using transformations (explaining the series of transformations used) I can describe transformations and/or dilations that produce similar figures and explain similarity of figures in terms of dilation and/or transformation. Learning Targets 1. Make sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 4. Model with mathematics. 5. Use appropriate tools strategically. 8. Look for and express regularity in repeated reasoning
