High Quality Content by WIKIPEDIA articles! In geometry, an enneagram is a nine-pointed geometric figure. It is sometimes called a nonagram. A regular enneagram (a nine-sided star polygon) is constructed using the same points as the regular enneagon but connected in fixed steps. It has two forms, represented by a Schlafli symbol as {9/2} and {9/4}, connecting every second and every fourth points respectively. There is also a star figure, {9/3} or 3{3}, made from the regular enneagon points but connected as a compound of three equilateral triangles.
