Center of a Circle Every circle has one special point that defines its entire shape — the center. Feb 7, 2026 · Solution For In the given figure, a circle with center O is shown. In the figure above, drag the orange dot around and see that the radius is always constant at any point on the circle. By definition, XY is a tangent to the circle at point P, which means XY touches the circle at exactly one point. A circle is defined as the locus of a moving point on a plane such that its distance from a fixed point on the plane remains constant or fixed. A chord PQ is drawn. The plural form is radii (pronounced "ray-dee-eye").
