Ympyrä kolmion sisällä

The image shows a triangle and a circle that contain the ratio 1.618, or the golden ratio. A similar idea is related also to other images of the visual geometry.

1 / 1.618 = 0.618

1 - 1.12 - 1.25 - 1.6 - 2.0

   Area of the triangle: 2 units²

Area of the circle: 1.1998 units²

Ratio between areas 

2 units² / 1.1998 units²  = 1.6669  => 1.6669 / 1.03* = 1.618

* 1.03 = the fatigue factor from time dilation
