What have you learned thus far about
similarity versus congruence? How do transformations that result in congruent
images differ from transformations that result in similar images? What
strategies can be used to trace the sequence of transformations, and how can
the information you obtain from the sequence help you to prove if the original
and final images are congruent or similar?

ReplyDeleteJournal Response: This week I learnedd that a similarity is a transformation where two images look the same but are not the same size. A congruency is two images that look the same but are faced in different positions. When a transformation results in a congruent image, it was translated, reflected or rotated. When a transformation results in a similar image, it can only be a dialation. A stagtey that I can use to trace the squence of the transformation is to look at the pre-iamge and then the new image to see how it was changed. If both coordinates were multipled by -1, then I know that it was a 180 degrees rotation. If every coordinate was moved 2 units left and 5 units up, then I know that it was a translation. I can prove that the image is congruent or similar by looking at the squence and seeing if it makes the new image bigger, smaller or if it stays the same. If it gets bigger or smaller, then it is a dialation. It it stays the same, then it is one of the three congruencys.
Great response Kyle! You should begin posting these in your blog so that you will begin to create your journal portfolio for the year!
