HSG.CO.A.3: Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.
What you'll learn
- Define symmetry as a transformation that maps a figure onto itself
- Identify all rotational symmetries of a given rectangle, parallelogram, trapezoid, or regular polygon
- Identify all lines of reflective symmetry for a given rectangle, parallelogram, trapezoid, or regular polygon
- Describe symmetries using precise transformation language (angle of rotation, line of reflection)
- Explain why certain figures have more symmetries than others based on their geometric properties
