Circle arc (Figure 2-11) is defined by its init position (X = 0, Y = 60000), radius R = 60000,

init angle α = 0

, and a sweep angle β = -135

. Line target position 25000, -42426.

Circle center coordinates (Xc, Yc) = (0 – Rcos90, 60000 – Rsin90) = (0,0). Circle end

point coordinates (Xc + Rcos(-45

), Yc + Rsin(-45

) = (42426, - 42426). Notice that

line L is parallel to the axis X meaning that

h = |0 - 42426| = 42426, ρ =|25000 - 0|

=25000 and

r can be calculated by

(3.1.2-8): r = (60000*60000 – 25000*25000 – 42426*42426)/(2*60000 – 2*42426) =
