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
Mickey Mouse degrees of a B.A. degree in Education Studies. One thing these courses share is that they are "vocational", which are perceived to be less intellectually rigorous than the traditional academic degrees. Defenders of these courses object that the derogatory comments made in the media rely on the low symbolic capital of new subjects and rarely discuss course contents beyond the titles. Another factor is the correct or incorrect perception that the take up of these subjects, and the decline of more traditional academic subjects like science, engineering, mathematics, is causing annual grade rise in the United Kingdom. The A-level in General
