Answer» In the given figure, M is the centre of the circle. Chords AB and CD are perpendiculat to each other. If $∠$ MAD = x and $∠$ BAC = y : (i) express $∠$ AMD in terms of x. (ii) express $∠$ ABD in terms of y. (iii) prove that : x = y.

In the given figure, M is the centre of the circle. Chords AB and CD are perpendiculat to each other. If ∠ MAD = x and ∠ BAC = y : (i) express ∠ AMD in terms of x. (ii) express ∠ ABD in terms of y. (iii) prove that : x = y.

Answer»

In the given figure, M is the centre of the circle. Chords AB and CD are perpendiculat to each other.

If $∠$ MAD = x and $∠$ BAC = y :

(i) express $∠$ AMD in terms of x.

(ii) express $∠$ ABD in terms of y.

(iii) prove that : x = y.
