Rotational Symetry


  1. In your own words explain what rotational symmetry is. Rotational Symmetry is a shape that can be rotated but can still look the same
  2. A shape has an order of rotational symmetry of 2. What does this mean? It mean that the shape has matched itself 2 times in the rotation
  3. How is rotational symmetry different from line symmetry? Line symmetry doesn't rotate
  4. What do you do to check if a shape has rotational symmetry? rotate it and if it matches it have rotational symetry
  5. Find pictures of 3 real life objects which have rotational symmetry (not shapes, objects e.g. foods, logos) and paste them into your post
