Angle trisection drawn through formula_25 to the semicircle, resulting in the intersection formula_28. The angle formula_48 generated by formula_49 and formula_50 is the angle formula_51 sought. Another means to trisect an arbitrary angle by a "small" step outside the Greek framework is via a ruler with two marks a set distance apart. The next construction is originally due to Archimedes, called a "Neusis construction", i.e., that uses tools other than an "un-marked" straightedge. The diagrams we use show this construction for an acute angle, but it indeed works for any angle up to 180 degrees. This requires three facts from geometry (at
98 Degrees 98 Degrees 98 Degrees (stylized as 98°) is an American pop and contemporary R&B vocal group consisting of four vocalists: brothers Nick and Drew Lachey, Justin Jeffre, and Jeff Timmons. The group was formed by Timmons in Los Angeles, California, although all of its members originate from Ohio.
