Lessons for G.CO.A.2
Combining transformations and the general formApplying a shift, a flip and a stretch to one parent graph together.Lesson
Rigid motions and congruenceTwo figures are congruent exactly when some sequence of slides, flips and turns carries one onto the other.Lesson
What rigid motions preserveLengths, angle measures, betweenness and parallelism all survive a rigid motion unchanged.Lesson
Rigid motions defined precisely, and what they preserveTranslations, reflections and rotations defined from segments, perpendicular bisectors and circles, and why each keeps distances and angles.Lesson
TranslationsDescribing a slide by how far the figure moves across and how far it moves up or down.Lesson
