Close to the golden ratio, better looking
The "golden section" is said to have been discovered by the ancient Greek mathematician Pythagoras and his school in the 6th century BC. Euclid said that the L line segment was divided into two parts, the longer part = the shorter part and the middle term of the total ratio, namely X :L=(LX):X, X≈0.618L.
They discovered this relationship in the composition of the five-pointed star, and used it to explain the artistic beauty of architecture and sculpture created by this relationship. The closer it is to the golden ratio, the more symmetrical it is and the more beautiful it looks.
