**Dividing A Line Segment**

The following algorithm produces a geometric construction that divides a line segment into two line segments where the ratio of the longer to the shorter line segment is the golden ratio:

- Having a line segment AB, construct a perpendicular BC at point B, with BC half the length of AB. Draw the hypotenuse AC.
- Draw a circle with center C and radius BC. This circle intersects the hypotenuse AC at point D.
- Draw a circle with center A and radius AD. This circle intersects the original line segment AB at point S. Point S divides the original segment AB into line segments AS and SB with lengths in the golden ratio.

### Famous quotes containing the words dividing and/or line:

“When a man and a woman have an overwhelming passion for each other, it seems to me, in spite of such obstacles *dividing* them as parents or husband, that they belong to each other in the name of Nature, and are lovers by Divine right, in spite of human convention or the laws.”

—Sébastien-Roch Nicolas De Chamfort (1741–1794)

“It may be the more

That no *line* of her writing have I,

Nor a thread of her hair,

No mark of her late time as dame in her dwelling, whereby

I may picture her there.”

—Thomas Hardy (1840–1928)
