Golden Rectangle Dissections

Author : Gavin Theobald

The golden rectangle {Rϕ} is a rectangle of proportions 1:(1+√5)/2 or approximately 1:1.6180. If a square is removed from one end of the rectangle then the remainder will have the same proportions as the original.

Triangle — Golden Rectangle (4 pieces)

This uses the TT2 technique. The dissection is hingeable.

Square — Golden Rectangle (3 pieces)

The dissection is translational.

Pentagon — Golden Rectangle (6 pieces)

Hexagon — Golden Rectangle (5 pieces)

The dissection is translational.

Heptagon — Golden Rectangle (7 pieces)

Octagon — Golden Rectangle (6 pieces)

Enneagon — Golden Rectangle (9 pieces)

Decagon — Golden Rectangle (6 pieces)

Dodecagon — Golden Rectangle (7 pieces)

Discovered by Harry Lindgren (1964).

Golden Rectangle — Pentagram (7 pieces)

Golden Rectangle — Hexagram (5 pieces)

Discovered by Harry Lindgren (1964).

The dissection is translational.

Golden Rectangle — Octagram {8/2} (8 pieces)

Golden Rectangle — Octagram {8/3} (7 pieces)

The two overlays show the strips before and after the modification of the octagram strip that saves a piece.

Golden Rectangle — Decagram {10/2} (10 pieces)

Golden Rectangle — Dodecagram {12/2} (9 pieces)

Golden Rectangle — Dodecagram {12/3} (9 pieces)

Silver Rectangle — Golden Rectangle (3 pieces)

The dissection is translational and hingeable.

Golden Rectangle — Domino (3 pieces)

The dissection is translational and hingeable.

Golden Rectangle — Greek Cross (5 pieces)

The dissection is translational.

Golden Rectangle — Latin Cross (5 pieces)
