A circle touches a given straight line and cuts off a constant length 2d from another straight line perpendicular to the first straight line. The locus of the centre of the circle, is

A circle touches x-axis and cuts off a constant length 2l from the y-axis. The locus of its centre of

A circle touches x-axis and cuts off constant length 2p from y-axis then the locus of its centre is

A circle touches x-axis and cuts off constant length 2p from y-axis then the locus of its centre is

If the straight line intersects the circle at two points, then the straight line is called a "_____" to the circle.

Straight line and Circle in complex number

A circle passes through a fixed point A and cuts two perpendicular straight lines through A in B and C. If the straight line BC passes through a fixed-point (x_(1), y_(1)) , the locus of the centre of the circle, is
