Geometry in Daily Life
In geometry, the centre of an object is a point in some sense in the middle of the object.
The centre of a circle is the point equidistant from the points on the edge. Similarly the centre of a sphere is the point equidistant from the points on the surface, and the centre of a line segment is the midpoint of the two ends.
