An important proportion that the ancient greeks used was the a0.

Step-by-step explanation:

Golden ratio is a special number found by dividing a line into two parts so that longer part is divided by the smaller one is equal to whole length divided by longer one.

a/b = (a + b)/a

a² = b(a + b)

a² = ab + b²

a² - ab - b² = 0

Now from the quadratic equation

a = [+b ± √(b² + 4b²)]/2

a = b×[1 ± √(5]/2

a/b = (1 + 2.236)/2 = 3.236/2 = 1.6180

This is the golden ratio is 1.6180 denoted by Phi.
