Warm-up Question (not in your book) Describe to a partner: Which triangle represents a rotation of Triangle ABC? Which triangle represents a reflection of Triangle ABC? Describe ways that you know the triangle you have chosen represents a rotation. Describe ways that you know the triangle you have chosen represents a reflection. Vocabulary to consider: Rotation Reflection Clockwise Counter-Clockwise Line of Reflection Map Quadrants I,II,III,IV Origin (0,0)

Page 47 Recall, the center is where you place your pencil when rotating your tracing paper clockwise or counter-clockwise.

A B C D E F G H The image shown to the right is an example of various Polygons (closed figures) that Jada might originally see somewhere in a coordinate plane. Choose one of the shapes shown to describe what information Jada would need to communicate if her new image is based on a translation and a reflection of your chosen pre-image to the right.

Page 50 The transformations that you perform here are simply reflections of the original figure (A). The size and shape of the figure are preserved, but will be mirrored either vertically or horizontally.

Page 51 What series of translations, reflections, rotations or combinations of these will bring Figure A to Figure B? Use your tracing paper to guide your movements. Write your sequences in the order you would use: First, I need to ___________________________________________ Second, I need to __________________________________________ Third, I need to __________________________________________ Translations should include: Direction – Up, Down, Left, or Right and distances moved in those directions. Rotations should include: The number of degrees / how far the Figure was turned and whether the rotation was clockwise or counter-clockwise. Reflections should include: The line of reflection such as “Over the x-axis or Over the y-axis, etc.”
