dodecagon

• “He gives the first a wrong date: he assures the world that there is no question about Scaliger's quadrature being wrong, in the eyes of geometers at least: and he states that Clavius mortified him {112} extremely by showing that it made the circle less than its inscribed dodecagon, which is, of course, equivalent to asserting that a straight line is not always the shortest distance between two points.”

• “The grid units and pixel primitives are of course different in the dodecagon scheme, but the code is otherwise almost identical to that used in the Demonstration and no additional steps are necessary.”

• “For an image x pixels wide and y pixels tall, there will be xy dodecagons and 2 (x – 1) (y – 1) triangles; the ratio of triangle area to dodecagon area for an a x a image reduces to”

• “He says in so many words that the periphery of the dodecagon is greater than that of the circle; and that the more sides there are to the inscribed figure, the more does it exceed the circle in which it is.”

• “You may do this: you may put the word _hexagon_ or _dodecagon_, or any other word describing a polygon in the place of _Circle_ in your proof, and the proof would be just as good as before.”
