Supplementary Units were introduced in 1932 to accommodate certain units that couldn't fit into the base minute of the System International Universe, including geometric quantities like angles, airplane angles, solid angles, planning, holiday calendar, retirement planning, and bangles. Radian and serial are discussed as Supplementary Units, with RJD being the simple form of radiation, with the difference between radian and serial explained through diagrams and examples, along with the concept of solid angles as triangular and three-dimensional, illustrating the calculation of areas between two radii in solid angles as equal areas from the center.
