Center of a Circle

Pronunciation: /ˈsɛn tər ʌv ə ˈsɜr kəl/ ?

All points on a circle are equidistant from the center of a circle.^[1] When we use a compass to draw a circle, the point of the compass is the center of the circle, and the stylus marks all points that are the same distance from the center.
