With 1998's Cowboy Bebop, one of the most acclaimed anime TV series ever (go read the comments index for it here on IMDb if you don't believe me!), Shinichiro Watanabe became a creative force to watch out for.
Angle finders use two hinged arms and an integrated protractor-like scale or digital device to read the angles of both inside and outside corners.When using an angle finder, the surface you are checking must be free of high spots and debris, and the protractor arms must be straight to ensure an accurate reading.ngle finders use two hinged arms and an integrated protractor-like scale or digital device to read the angles of both inside and outside corners.
The problem of angle trisection reads: Construct an angle equal to one-third of a given arbitrary angle (or divide it into three equal angles), using only two tools: 1  an unmarked straightedge and. 2  a compass.sing only an unmarked straightedge and a compass, Greek mathematicians found means to divide a line into an arbitrary set of equal segments, to draw parallel lines, to bisect angles, to construct many polygons, and to construct squares of equal or twice the area of a given polygon.
