A copy of a geometric figure The copy holds certain properties (Similar to copy and paste on the computer) Pre – image = original figure Image = new (copied) picture

2 basic types: 1. Rigid Transformations – Definition: the pre image and image both have exact same size and shape – 3 types of rigid are: – A. translations – B. reflections – C. rotations 2. Non-rigid transformations

 Non rigid transformation: ◦ Definition: it can do stretching and shrinking and twisting

 tion-geometry.html tion-geometry.html  This is a resource, in case you need to refer to later

 nsformations/transformations-2/ nsformations/transformations-2/

 Summary:  How can you represent a transformation in the coordinate plane?  Put answer in your notebook  Date and label

 Do Now:  Create a venn diagram for the two words 1. rigid transformation 2. non-rigid transformation in your notebooks

 Definitions (in terms of lines parallel or perpendicular, angles, circles, segments) 1. Reflections 2. Rotations 3. Translations

 Pictures/videos to help with definitions

 Pg. 551 ◦ #42, 43, 44 then describe to me using the terms learned today (translation, reflection, rotation) about how transformation relate to slope  Create a brochure of terms, large frayer diagram, and/or song with dance step / beat that will mimic reflection or translation

 Honors: read article, write synopsis on the article, but they must include the terms in the article  Paragraph, use of proper grammar, math terms, math connections, good spelling,  Type on edmodo and send to me or we will use gaggle

 How can you verify that your rule is correct for a specific transformation? (ticket out)

 D.E.A.R 10 minutes  At the end of today’s D.E.A.R please send me a message on edmodo describing your what you read today; you will have 5 minutes

 Define the transformation type 1. Rotation 2. Line of reflection And 3. What kind of lines are y = 2 and x = 5 (describe the orientation of the line)

 Reflections and rotations  Use of paper plates  Ordered pairs  Coordinate plane

 Define reflection  Define rotation  Define composition of transformation

 9-2 puzzle, connect dots

 How can you change a figure’s position without changing its size and shape? Why might you want to? (ticket out)

 D.E.A.R 15 minutes  Do now: what is the name of the original figure in transformations? What is the name of the new figure?  Test on unit 2 rotations, reflections, translations

 D.E.A.R 15 minutes  Do now: solve an algebraic equation

 Go over yesterday’s test  Work on projects ◦ Wallpaper or wrapping paper (your translation design) ◦ If did not turn in your notebook ready, get it ready now and turn in before you leave (it is late, but you will receive at least a B if you have everything and organzied)
