Unit 1 begins with exploring and verifying the properties of rotations, reflections, and translations. By using coordinates, you will describe the effects of dilations, translations, rotations, and reflections. You will understand that two figures are congruent or similar if one can be obtained from the other by a sequence of rotations, reflections, or translations. Lastly, you will examine the properties of the angles created when parallel lines are cut by a transversal.
