Equation of any circle, with any radius, and its center at any point: [ x - (x-coordinate of the center) ]2 + [ y - (y-coordinate of the center) ]2 = (radius of the circle)2
Formula of a circle in a Cartesian plane: (x-h)^2+ (y-k)^2 = r^2 where the center is at (h,k) and the radius is r.
Its simply called the "center point" or "center". There is no fancy term for it.
The angle bisectors of a triangle are the lines which cut the inner angles of a triangle into equal halves. The angle bisectors are concurrent and intersect at the center of the incircle.
If you mean equilibrium or centre of balance then it is at where its diagonals intersect. The intersection of the diagonals is also the centre of symmetry; a rhombus has 2-fold rotation symmettry.
The center of the cartesian coordinate plane is called the origin and is located at the point (0,0), where the x and y axis meet.
Cartesian coordinate system
Cartesian plane is the x-y coordinate plane for graphing. x axis goes horizontally, neg to left and pos to the right. y-axis is vertical, neg is down, pos is up. The center where both x and y intersect is the origin, 0 for both x and y. This divides the plane into 4 parts called quadrants.
It is called the origin.
The centre of a coordinate plane is the point (0,0), also called the origin.
the very center of a coordinate plane is called the origin or (0,0) :D
The center of a coordinate plane is called the origin. The origin is the ordered pair (0,0).

By using Cartesian equations for circles on the Cartesian plane
'Centre of mass' is a place, i.e. a point, in space. It can be described by its coordinates . . . lengths (x, y, z) in Cartesian coordinates, or some combination of lengths and angles in other coordinate systems.
In the system of Cartesian coordinates in geometry, the x-coordinate is the location in the horizontal direction (nominally left and right) while the y-coordinate is in the vertical direction (up and down). The line along which x values are measured is the x-axis. An x-coordinate to the left of center (zero) is negative, and to the right is positive. (In three dimensions, the x and y form a horizontal plane and the z coordinate is measured along the vertical axis.)
That's a "central angle", but the part that really fascinates me is this: What would it look like if you hadan angle whose vertex was in the center of the circle and whose sides didn't intersect ? ? ?
