The highest symmetry irregular icosagons are d20, an isogonal icosagon constructed by ten mirrors which can alternate long and short edges, and p20, an isotoxal icosagon, constructed with equal edge lengths, but vertices alternating two different internal angles.
Coxeter states that every zonogon (a 2m-gon whose opposite sides are parallel and of equal length) can be dissected into m(m-1)/2 parallelograms. [3] In particular this is true for regular polygons with evenly many sides, in which case the parallelograms are all rhombi.
Cleek – A metal-headed golf club having an elongated blade with little loft, equivalent to a one or two iron in a modern set of clubs. Lofter – A metal-headed golf club with a moderate loft ranging from a modern five iron to an eight iron. Niblick or Rut Niblick – a trouble club and pitching iron and generally the most lofted of the 19th ...

The rules of golf consist of a standard set of regulations and procedures by which the sport of golf should be played. They are jointly written and administered by The R&A (spun off from The Royal and Ancient Golf Club of St Andrews in 2004) and the United States Golf Association (USGA). The R&A is the governing body of golf worldwide except in ...
The class of wedges grew out of the need for a better club for playing soft lies and short shots. Prior to the 1930s, the best club for short "approach" shots was the "niblick", roughly equivalent to today's 9-iron or pitching wedge in loft; however the design of this club, with a flat, angled face and virtually no "sole", made it difficult to use in sand and other soft lies as it was prone to ...
