Unit 8 : Angles Properties in Circles Learning Objectives The students should be fitted to: severalise various partlys of a circle. assert the properties of harmonizes of a circle. state and go for the holding of angles at the displace. state and apply the property of angles in the same department. spot 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. recognize the properties of the tangents to a circle. state and apply the alternate part theorem. Circles 1.Parts of a circle A circle is a shut curl up in a plane such that whole points on the curve be equidistant from a primed(p) point. The given outdo is called the radius of the circle. A chord is a phone line segment with its end points on the circle and a diameter is a chord passing throu gh the centre. An dismissal is a part of the circle. A segment is the region jump by a chord and an arc of the circle. A domain is the region bound by two radii and an arc. 2.Chords of a circle next are properties on chords of a circle. All these facts can be turn up by the properties of congruent triangles.
