Assertion(A) At a point P of a circle with centre O and radius 12cm , a tangent PQ of length 16cm is drawn. Then, OQ=20cm . Reason (R ) The tangent at any point of a circle is perpendicular to the radius through the point of contact.

A Tangent to a circle is perpendicular is perpendicular to the radius through the point of contact.

A tangent at any point of a circle is perpendicular to the radius through the _____.

The tangent at any point of a circle is ............ to the radius through the point of contact.

The x-intercept of the tangent to a curve is equal to the ordinate of the point of contact. The equation of the curve through the point (1,1) is

The perpendicular from the origin to the tangent at any point on a curve is equal to the abscissa of the point of contact.Also curve passes through the point (1,1). Then the length of intercept of the curve on the x-axis is
