ByVocabulary. Transformation symmetry line symmetry line of symmetry rotational symmetry. Transformation. A transformation is a general term for four specific ways to manipulate the shape of a point, a line, or figure.

BySymmetry and Reflections. Describe and identify lines of symmetry. Create reflections on a coordinate plane. Objectives. Vocabulary. If a line can be drawn through a figure so that the two halves match like a mirror image the figure has line symmetry .

By9.5 : Symmetry. I can identify line and rotational symmetries in two‐dimensional figures. I can identify plane and axis symmetries in three‐dimensional figures. If the images to the right describe symmetry, in your own words, define symmetry:. Vocabulary!. Example 1:.
