"Geometric construction shows intersecting circles, reference axes, and projected points across panels a to c. Labels mark centers, radii, angles, heights, and distances, including R, L, h c, theta, alpha, beta, gamma, and rho c. Insets for directions B, C, and D show local coordinate axes and angular relationships around a small central shape."
