what is the shape of a crescent moon
Crescent The crescent shape consists of a circular disk with a segment of another circle removed from its edge, so that what remains is a shape enclosed by two circular arcs of different diameters which intersect at two points (usually in such a manner that the enclosed shape does not include the center of the original circle). As such, it belongs to the class of figures known as lune in planar geometry. The tapering towards the points of intersection of the two arcs are known as the "horns" of the crescent. The classical crescent shape has its horns pointing upward (and is often worn as horns when worn as a crown or diadem, e.g. in depictions of the lunar goddess, or in the headdress of Persian kings, etc.[7]
Royal Crescent The Royal Crescent is a row of 30 terraced houses laid out in a sweeping crescent in the city of Bath, England. Designed by the architect John Wood, the Younger and built between 1767 and 1774, it is among the greatest examples of Georgian architecture to be found in the United Kingdom and is a Grade I listed building. Although some changes have been made to the various interiors over the years, the Georgian stone faÃ§ade remains much as it was when it was first built.
