Standards addressed:
MGSE.9-12.G.CO.2. Represent transformations in the plane using transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not.
MGSE.9-12.G.CO.3 Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.
MGSE.9-12.G.CO.4 Develop definitions of rotations, reflections and translations in terms of angles, circles, perpendicular lines, parallel lines and line segments.
MGSE.9-12.G.CO.5. Given a geometric figure and a rotation, reflection or translation, draw the transformed figure using graph paper, tracing paper or geometry software. Specify a sequence of transformations that will carry a figure onto another.
MGSE.9-12.G.SRT.1 Verify experimentally the properties of dilations given by a center and a scale factor.


Learning Targets/Success Criteria:
All learning targets/success criteria for Unit #1 including:
--I can represent transformations visually with manipulatives or software.
--I can describe transformations as functions with inputs and outputs.
--I can compare transformations that preserve congruence with those that do not.
--I can describe lines of symmetry in rectangles, parallelograms, trapezoids, and regular polygons in terms of rotations and reflections that carry each shape onto itself.
--I can develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments.
--When given a geometric figure and a specific transformation, I can draw the transformed figure using graph/tracing paper or geometry software.
--Given two figures, I can specify a sequence of transformations that will carry one figure onto another.
--Given a center and a scale factor, I can verify properties of dilations.
