1. what is the difference between a pre image and an image? how can you tell them apart? 2. using a white board or graphing technology like geogebra be able to preform a reflection for a pre image over the x axis, y axis, line y=x or line y = -x. what is the relationship to the segment formed by corresponding vertices and the line of reflection? 3. using a pre image you should be able to preform a translation and a rotation and write mathematical notation for each a. show the transformation and write he function rule for a translation if you want to move the pre image seven units to the left and two units up? b. what do you need to know in order to do a rotation?
