Describing a translation

Describing a translation.

  • Match corresponding vertices before describing a transformation.
  • Reflection: mirror line. Rotation: centre, angle and direction. Translation: vector.
  • Enlargement: centre and scale factor. Apply combined transformations in the stated order.

Example 1
