MS Math SPED Resource Map

● Observe that orientation of the plane is preserved in rotations and translations, but not with refections. ● Understand characteristics of dilations, translations, rotations, and refections of two-dimensional fgures on the coordinate plane (describing transformations as functions takes place in Secondary Mathematics I). ● Effects of transformations might include: size/shape does not change in translations, refections and rotations; orientation changes with refections. ● Use informal arguments (proofs occur in Secondary Mathematics II) to establish facts about:

1. the angle sum of triangles. 2. exterior angle of triangles. 3. about the angles created when parallel lines are cut by a transversal. 4. the angle-angle criterion for similarity of triangles.
