We can say that the diagonal of a regular pentagon are in golden ratio to its sides. The point of intersection of two diagonals of a regular pentagon are said to divide each other in the golden ratio (or "in extreme and mean ratio").

We can use these triangles to find the ratio of a diagonal length to a side length of the pentagon. ... This is called the Golden Ratio. For any regular pentagon with side s and diagonal length d, the ratiod/s = the golden ratio.
