When a line divides another in two equal parts, it is called a bisector. If the bisector happens to cross the other line at right angles, it is called a perpendicular bisector.
One possible way: draw 21 radii, each forming an angle of 17.142857.. degrees with another radius. Another option: the question does not require the 21 parts to be equal. So make twenty cuts where each cut divides a segment into two (equal or unequal) parts.
bisect is to divive into equal parts.
Each inequality divides the Cartesian plane into two parts. On one side of the line the inequality is satisfied while on the other it is not. A system of inequalities divides the plane into a number of such parts and the intersection of these parts in which the inequalities are true defines the the required region.
The Equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Lines of latitude are parallel to the Equator both to the north and to the south.
The equator is the parallel that divides the Earth into two equal parts, with one half in the Northern Hemisphere and the other half in the Southern Hemisphere.
The equator, which is a line of latitude and divides the Earth into northern and southern hemispheres. And prime meridian, which is a line of longitude and divides the Earth into eastern and western hemispheres.
The equator.

The equator is the parallel that divides the Earth into two equal parts: the Northern Hemisphere and the Southern Hemisphere. It is an imaginary line situated halfway between the North Pole and the South Pole.
The Equator divides the island of Borneo into roughly equal northern and southern parts.
The parallel is called the equator.

the middle of something divides it into two equal parts not the center because the center divides it into 4 equal parts
