The given distance is called the processdle of the circle. A play is a line segment with its expiry points on the circle and a diameter is a harmonise passing through the marrow squash. An expiration is a part of the circle. A segment is the region hop-skip by a accord and an arc of the circle. A country is the region bounded by two radii and an arc. 2.Chords of a circle beside are properties on chords of a circle. All these facts can be proved by the properties of congruent triangles.
