Surface Areas of the pentagon

Viisikulmion pinta-alat

In the pentagon image, the top part is marked with honey cells and the lower part with stars. In the drawing, the upper triangle has the width of 100 units. The image areas are below. The ratio of the areas stays by any dimensions change in the drawing. The idea is the same as the issues and phenomena have.

By knowing one case, the other cases are known. Later observed the pentagon areas having the same ratio as the matter has under load. This is visual geometry of the forces in the matter.

 4755.3078 / 1816.3659 = 2.618

The total area of a pentagon

4755.3078 + 1816.3659 = 6571.6737

The total surface area ratio to the smaller area

6571.6737 / 1816.3659 = 3.618

1.618 review

1.618 x 1.618 = 2.618

1.618 +1 = 2.618

2.618 +1 = 3.618

100 / 1.618 = 61.8

Is there any other pattern, which has potential for the pentagon? The golden section ratio has an undeniable connection to pentagon and by calculating made reviews. (335)
