Q.

A square is inscribed in the circle x2+y2-2x+4y+3=0, whose sides are parallel to the coordinate axes. One vertex of the square is

View Answer

Correct choice: B

Explanation:

Obviously the centre of the given circle is (1,-2). Since the sides of square are parallel to the axes, therefore, first three alternates cannot be vertices of square because in first two (a and b) y = -2 and in (c) x = 1, which passes through centre (1,-2) but it is not possible. Hence answer (d) is correct.
