Transformations and Art Translations, Rotations, and Reflections

What is a transformation? A TRANSFORMATION is a term used to describe four specific ways to move shapes. There are three TRANSFORMATIONS that result in congruent figures: ROTATION: TURN TRANSLATION: SLIDE REFLECTION: FLIP Another type of transformation is a dilation, which changes the size of the object. We will discuss dilations later.

Slide, Flip, or Turn ?

Rotation or Turn! One hand in this sculpture by Rodin is rotated or turned to create the other hand! Now you try: http://www.mathsisfun.com/geometry/rotation.html

Slide, Flip, or Turn ?

TRANSLATION OR SLIDE! This painting is by John Beerman and the trees and clouds are examples of a slide or translation. Now you try: http://www.mathsisfun.com/geometry/translation.html

Slide, Flip, or Turn ?

FLIP or REFLECTION! This piece, that was created by Devorah Sperber using 5184 spools of thread, is titled “After the Mona Lisa 2” and is a great example of a reflection. Now you try: http://www.mathsisfun.com/geometry/reflection.html

Your Assignment! Create a symmetrical work of art using ONLY squares, triangles, and rectangles. Plan your design and be precise in your drawings and transformations. You must include translations, rotations, and slides and you must record the coordinates of the original as well as the translated figures and describe the translation of each.
