Standards Addressed:
MGSE.9-12.G.CO.3 Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto to itself.

MGSE.9-12.G.CO.5 Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure. Specify a sequence of transformations that will carry a given figure onto another.


Learning Targets/Success Criteria:
--I can graph a image and identify the image's coordinates given a sequence or composition of transformations.
--I can identify the rule or sequence of transformations given the pre-image and image.
--I can describe the lines of symmetry in rectangles, parallelograms, trapezoids, and regular polygons in terms of rotations and reflections that carry each shaped onto itself.
--I can recognize/identify a line of symmetry.
--I can recognize the number of lines of symmetry in a given figure.
--I can recognize/identify the rotational symmetry of a figure.
--I can specify if/how a figure can be mapped onto itself by identifying lines of symmetry and/or angles of rotation.


Introduction/Connection: Introduce/revisit terms: students will complete selected problems on Investigating Symmetry (attached below).


Direct Instruction/Guided Practice:
--Guided practice problems on Compositions of Transformations 2 (attached below). Students will work together to create rules for the transformations.
---Review vocabulary listed above.
--If time, guide students in identifying rotational symmetry and line symmetry using attached w/s below.
