‘Their centers thus lie on the trisectors of the angles adjacent to that line.’

‘If the angles of any triangle be trisected, the triangle, formed by the meets of pairs of trisectors, each pair being adjacent to the same side, is equilateral.’

‘We no longer look kindly on angle trisectors and circle squarers.’

‘Due to the definition of rotation angles, A, B, and C are the intersections of trisectors.’

‘A method to obtain a good approximation to the trisector of an angle by Euclidean construction is also given.’
