Lesson Summary

This text covers a number of topics in mathematics including translation, reflection, rotation, lines of symmetry, order of rotational symmetry, reflections, rotations, and translations. All of these topics involve changes in position, size, or rotation of a shape in order to transfer it between other shapes. For example, a translation involves shifting a shape in either vertical or horizontal directions whereas a rotation is done about a point, and a reflection is done across a mirror line. Furthermore, the text involves a number of activities including drawing reflections and rotations of certain shapes and writing down the number of lines of symmetry for each given shape in addition to the order of rotational symmetry.
