1. Transformation

   • Rotatioin
   • Reflection
     • A shape is symmetrical if both sides of it are the same when a mirror line is drawn.
     • This shape is symmetrical. It has reflection symmetry. It has one line of symmetry.
     • When you fold a shape along a line of symmetry, one half fits exactly over the other. When you put a mirror on a line of symmetry and look from either side, the shape looks like the original.
     • Line of symmetry: a mirror or fold line. Reflection symmetry: when there are one or more lines of symmetry
