Exploring mirror symmetry

A mirror line divides a picture into reflected halves. Corresponding marks sit the same distance from that line.

Worked example

A dot one square left of the center line belongs one square right in the reflected half, at the same height.

Try it step by step

1. Mirror Picture

   Complete the right side as a reflection of the left.

2. Symmetry Butterfly

   Decorate both wings with matching reflected marks.

3. Tangram

   Move and rotate seven pieces to cover the silhouette without overlaps.

A useful hint

Reflection reverses left and right. Copying the same left-to-right order can produce a translation instead of a mirror image.
