Practise reflection questions by counting perpendicular distances from the mirror line and plotting the reflected vertices accurately.

How this is tested

  • Reflect a shape in a given line such as y = x or y = -1 on the grid accurately.
  • Keep each vertex the same perpendicular distance from the mirror line.
