Question types: Complete the shape over the mirror line

Rule: Line symmetry

Each point has its image on the other side of the mirror line, just as far from it, straight across.

Example: A square 2 cells left of the line has its image 2 cells right of it.

Watch out: The image is not shifted or turned: in a mirror the left side ends up on the right.

Sample questions

  1. Question 1 Easy

    Complete the figure so that it is symmetric about the dashed line. Which picture shows it done correctly?

    1. A)
    2. B)
    3. C)
    4. D)
    5. E)
    Show the solution
    Answer: E) picture E

    How it works: Every square has its image on the other side of the line, just as far from it. The right picture is E.

  2. Question 2 Normal

    1. A)
    2. B)
    3. C)
    4. D)
    5. E)
    Show the solution
    Answer: D) picture D

    How it works: Every square has its image on the other side of the line, just as far from it. The right picture is D.

  3. Question 3 Hard

    1. A)
    2. B)
    3. C)
    4. D)
    5. E)
    Show the solution
