Octadecagon Octadecagon An octadecagon (or octakaidecagon) or 18-gon is an eighteen-sided polygon. A "regular octadecagon" has a Schläfli symbol {18} and can be constructed as a quasiregular truncated enneagon, t{9}, which alternates two types of edges. As 18 = 2 × 3, a regular octadecagon cannot be constructed using a compass and straightedge. However, it is constructible using neusis, or an angle trisection with a tomahawk. The following approximate construction is very similar to that of the enneagon, as an octadecagon can be constructed as a truncated enneagon. It is also feasible with exclusive use of compass and straightedge. The "regular
How Could an Angel Break My Heart of the song has the storyline laid out a little differently, with Babyface singing back to her and duetting with her from the second verse. Babyface's vocals replace Kenny G's saxophone parts. This CD has an error in the tracks. Despite being listed in this way the two instrumentals have been put on in the reverse order. This can be heard clearly as Kenny G's saxophone parts are present on track four and absent in track three, whereas in the vocal versions of the song, this is quite the opposite.
