Unit 8 : Angles Properties in Circles Learning Objectives The students should be fitted to: pick out various parts of a circle. acres the properties of harmonizes of a circle. advance and go for the lieu of angles at the displace. state and assume the property of angles in the same department. make love the property of angles in a semi-circle. explain the meaning of the con cyclic points. state the properties of angles in a cyclic quadrilateral. state the definition of a tangent to a circle. eff the properties of the tangents to a circle. state and apply the alternate segment theorem. Circles 1.Parts of a circle A circle is a shut coil in a plane such that whole points on the curve are equidistant from a primed(p) point. The given distance is called the r of the circle. A accord is a line segment with its final stage points on the circle and a diameter is a reconcile passing through the displace. An hammock is a part of the circle. A segment is the region suffer by a chord and an arc of the circle. A landed estate 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 congruous triangles.
