  1. 2. - moves every point of a figure or a space by the same distance in a given direction
  2. 5. - the covering of a plane using one or more geometric shapes, called tiles, with no overlaps and no gaps
  3. 6. - a 'flip' of an object across a line
  4. 8. - a function from a metric space into itself that satisfies the identity for all points, where is the distance from to and is some positive real number
  5. 9. - any rotation is a motion of a certain space that preserves at least one point
