Drawing Daisy Wheel Angles

250 x 160 mm / 6 pages / full colour

The compass drawn daisy wheel is a precision geometrical protractor giving six 60 degree sectors that can be geometrically subdivided into 30 degree, 15 degree and smaller subdivisions or combined to give greater angles such as 90 degrees and upwards.

The wheel is also a major source of triangulation. The six petal tips on the wheel's circumference can be connected to generate 30 60 90 degree triangulation but also, perhaps unexpectedly, four and six point rectangles. Dividing the four point rectangle along its diagonal produces two identical 30 60 90 degree triangles that are perfect set squares.
