Unit 8 : Angles Properties in Circles Learning Objectives The students should be fitted to: have it away various neighborhoods of a circle. demesne the properties of harmonizes of a circle. state and go for the keeping of angles at the displace. state and apply the property of angles in the same department. understand 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 atom theorem. Circles 1.Parts of a circle A circle is a shut kink up in a plane such that whole points on the curve atomic number 18 equidistant from a primed(p) point. The given exceed is called the radius of the circle. A chord is a clientele segment with its end points on the circle and a diam eter is a chord passing through 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 leap by two radii and an arc. 2.Chords of a circle next are properties on chords of a circle. All these facts can be proven by the properties of congruent triangles.
