Unit 10 focuses on refelction and symmetry. In this unit, we will take another look at geometry, with an emphasis on symmetry. Many objects in nature such as flowers, insects ,and humans have symmetry. just a few. Symmetry is all around in buildings, furniture, clothing, and paintings.
The class will focus on reflectional symmetry, also called line symmetry or mirror
symmetry, in which half of a figure is the mirror image of the other half. In class will use a tool called a transparent mirror to see and trace the mirror image of an object.
Geometry is not only the study of figures (such as lines, rectangles, and circles), but also the study of transformations or “motions” of figures. These motions include reflections (flips), rotations (turns), and translations (slides). We will use these motions to create pictures called frieze patterns.
