Transformations and symmetry
Explain what changes and what is preserved by moving, reflecting, and rotating shapes.
Meaning
Translations, rotations, and reflections change position or orientation while preserving lengths and angles. Symmetry can mean a figure coincides with itself after a transformation.
Example
Practice for this concept
Scope and references
Topics
Translations, reflections, rotations, line and point symmetry
Learning goal
Explain what changes and what is preserved by moving, reflecting, and rotating shapes.
Helpful background
Compare positions, directions, and corresponding points.
Transformations and symmetry
These choice exercises use stated geometric conditions. They do not establish construction, drawing, spatial manipulation, written proof, or mastery of the whole geometry area.
