Answer 2

• Supplementary units are the dimensionless units that are used along with the base units to form derived units in the International system. The class of supplementary contains only two purely geometrical units, that is the radian and the steradian.

• radian - a unit of measurement of angles equal to about 57.3°, equivalent to the angle subtended at the centre of a circle by an arc equal in length to the radius.
• steredin - the SI unit of solid angle, equal to the angle at the centre of a sphere subtended by a part of the surface equal in area to the square of the radius.
