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.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.


Learning Targets/Success Criteria:
--I can identify the scale factor of a dilated image.
--Given a scale factor, I can apply a dilation to a pre-image to graph the image and identify the image points.
--I can recognize that a dilation changes the size of a figure and does not preserve congruence.
--I can recognize that rotations, reflections and translation preserve side lengths and angle measures creating congruent figures.

Students will complete the following IXLs (due at the end of the block):
--L16 Dilations: find the coordinates
--L18 Dilations: find the scale factor
--L3 Translations: Find the coordinates
--L6 Reflections: find the coordinates
--L9 Rotations: find the coordinates
