Chapter 9 Vocabulary and Formulas, page 1 of 1 DIRECTIONS 1. DEFINITIONS OR FORMULAS For each vocabulary term or formula, write out the definition of the term or give the formula. If you are giving a formula, define your variables (e.g., don't write just A = b x h, write Area = Base x Height or A = b x h, and define A = area, b = base and h = height). 2. SKETCH A simple sketch (picture) is required for each term unless specified by: NO PICTURE. For terms that require a sketch; draw a simple and labeled sketch of the item you are defining. Recommendation: Don't waste time on fancy graphics Section 9.4 1. Line of Symmetry 2. Reflection Symmetry for Plane Figures 3. Rotation Symmetry for Plane Figures 4. Center of Rotation 5. Plane of Symmetry 6. Reflection Symmetry for Space Figures 7. Rotation Symmetry for Space Figures 8. Axis of Symmetry (for Space Figures)
