Geometric fan diagram with proportional divisions
A triangle and a figure whose segments run quadruple, double, sextuple and octuple
A geometric fan spreads from a single apex down to a horizontal base line divided into segments, closing into a kite below; a small triangle is drawn at the top of the sheet. The notes label the segments with proportional ratios, relating the marked divisions to one another as quadruple, double, sextuple and octuple.

Triangle marked 4-4 4
A small triangle is drawn at the top of the sheet, annotated with the figures 4-4 4.
Line divided into proportional segments
A figure carries lettered points a, b, c, d, e, f, g, h, and the notes give the ratios of its segments: a b quadruple, c d double, e f sextuple, g h octuple. The proportions relate the marked divisions of the base line to one another.
