Q1.
Look at the following shapes. What do you notice? Discuss.
The two designs printed in the book.
Answer

Both designs are made from the same small shape — a rhombus (diamond).

The two designs printed in the book, made of rhombus tiles.

Here is what to notice:

  • Every piece is the same rhombus, only turned in three different ways.
  • Three rhombuses meeting at a point look like a box (a cube).
  • The two designs use the same pieces in the same places — only the colours are different.
  • There are no gaps and no overlaps anywhere.
Why it happens: All the sides of a rhombus are equal, so three of them fit neatly round a point. Our eyes then read the flat picture as a solid box.
Try This: Colour the whole design in one colour. The boxes disappear and you see only flat diamonds.
