WebIn the figure, given below, AB and CD are two parallel chords and O is the centre. If the radius of the circle is 15 cm, fins the distance MN between the two chords of lengths 24 cm and 18 cm respectively. WebGiven. Two chords AB and CD of the circle intersect each other at right angles. Concept used. Two angles subtended by the arc on the circle are equal. Calculation. In the given figure. Arc AD substend ∠ ACD and ∠ ABD. ⇒ ∠ ACD = ∠ ABD = y. Two chords intersect at right angle. In Δ AEC. ∠ CAE = x° ∠ AEC = 90° ∠ ACE = y°
