Igse Geometry Angle Properties Of Circles Part 1 Youtube In this video, we will learn the first three properties of circles.property 1: perpendicular line from the centre bisects the chord.property 2: equal chords. The central angle of a circle is twice any inscribed angle subtended by the same arc. angle inscribed in semicircle is 90°. an angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment. the opposite angles of a cyclic quadrilateral are supplementary. Tangents to the circle from a point have the same length: t a = t c. ta = tc t a = t c. opposite angles in a cyclic quadrilateral: ∠ a b c ∠ c d a = 1 8 0 ∘. \angle abc \angle cda = 180^ \circ ∠abc ∠c da = 180∘. here are additional basic properties that are useful to know: equal arcs subtend equal angles and vice versa. Example 2: consider the circle given below with center o. find the angle x using the circle theorems. solution: using the circle theorem 'the angle subtended by the diameter at the circumference is a right angle.', we have ∠abc = 90°. so, using the triangle sum theorem, ∠bac ∠acb ∠abc = 180°.
