Abstract: A plotter apparatus inscribes a polygon in a circle, and includes a ruler body, a first slider, a second slider, multiple brachiums, and a nib member. The ruler body comprises a knap, and a first ruler groove and a second ruler groove to allow movement of the first slider and the second slider. The brachiums are connected across the ruler body via pivots. The nib member allows the drawing of the circle. A fourth brachium is attached to a predetermined numbered hole on a second and a third brachium as per the number of sides required on the polygon. The length of each side of the polygon is retrieved between the knap and a slider. Cyclic arcs, with the determined length as a length of one side of the polygon, are drawn along the circumference of the circle. The arc intersections on the circle are joined together to define the polygon.
