|
The golden ratio φ is a mathematical constant obtained as the ratio of longest-to-shorted side lengths in a rectangle constructed so that when it is partitioned into a square and new rectangle, the new rectangle has the same ratio of side lengths as the original. The golden ratio has value of approximately 1.618.
Golden ratio is a middle school-level concept.
Prerequisites
| Geometry: | Geometry is the branch of mathematics that studies figures, objects, and their relationships to each other. This contrasts with algebra, which studies numerical quantities and attempts to solve equations. |
| Rectangle: | A rectangle is a quadrilateral with opposite sides of equal length and with four right angles. |
| Square Root: | A square root of x is a number r such that r*r = x. |
