A line which divides a shape in two is called a bisector.
This would be known as the Equator
When a ray divides an angle(Which is formed by 2 straight lines) in half that is equally on both the sides, it is termed as Angle Bisector.
Symmetry
That is the correct spelling of "bisect" (to divide equally in half, as in geometry).
to cut something in half equally
A line that divides an angle in half is called the angle bisector. It creates two equal angles from the original angle, ensuring that each of the resulting angles measures half the size of the original. Angle bisectors are commonly used in geometry and can also be applied in various fields, such as engineering and architecture.
Half a circle is called a "semicircle" in geometry.
A line that divides a shape or area into two equal parts is known as a "bisector." In geometry, this can refer to a line segment, angle bisector, or median, depending on the context. For example, the perpendicular bisector of a line segment splits it into two equal lengths at a right angle.
The sagittal plane divides the mouth into a right and left half.
A bisector divides an angle in half (usually in the form of a line passing through the centre of the angle).
The line that divides the Earth in half horizontally is known as the Equator. It is located at 0 degrees latitude and divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
