Hendecagon of a regular hendecagon is still impossible even with the usage of an angle trisector. It can, however, be constructed via neusis construction and also via two-fold origami. Close approximations to the regular hendecagon can be constructed, however. For instance, the ancient Greek mathematicians approximated the side length of a hendecagon inscribed in a unit circle as being 14/25 units long. The following construction description is given by T. Drummond from 1800: On a unit circle: The "regular hendecagon" has Dih symmetry, order 22. Since 11 is a prime number there is one subgroup with dihedral symmetry: Dih, and 2
How Long, How Long Blues his vocals have also been described as emotionally detached, high-pitched and smooth, with clear diction. Blackwell's single-string jazz guitar lines provided the role of a responsorial voice as well as rhythmic chording. "How Long, How Long Blues" was Carr and Scrapwell's biggest hit.
