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 Target/Success Criteria:
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.


Introduction/Connection: students will complete Mixed Review of Transformations (front only--attached below).


Direction Instruction/Guided Practice:
--review bellringer
--finish/review dilations foldable (if needed)
--practice dilations using IXL

Resources: IXL

Assignment: Students will complete the following IXLs (due date 8/23 @ 8am):
1) L16 Dilations: find the coordinates (shortcut 5KZ)
2) L18 Dilations: find the scale factor (shortcut ZDM)
