Assertion(A)Reason(R)In the given fifure, a quad.ABCD isIn two concentric circles, the chorddrawn to circumscribe a given circle,of the larger circle, which touchesas shown. the smaller circle, is bisected at theThen,AB+BC=AD+DC. point of contact.
The correct answer is (a)/(b)/(c)/(d).
for a circumscribed circle by a quadrilateral , Sum of opposites sides of the quadrilateral are equal not sum of adjacent sides .
chord of larger circle will be a tangent to smaller circle at point of contact and radius through that point is perpendicular to chord and bisects it.
Assertion is wrong and Reason is true
