1. Given that points are and
From figure, is equilateral
Hence,
or (for first quadrant) or (for fourth quadrant). Then possible coordinates are
Similarly, for second quadrant, the point is
And for third quadrant, the point is
1. Case (i)
If , then
Hence, point is . By symmetry, all possible points are
Case (ii)
And
Hence, point is .by symmetry, all possible points are
c.
Let . Area of is
and
Hence, has coordinates . By symmetry, all possible coordinates are
From the above figure has coordinates
By symmetry, all possible coordinates are
d.
units radius
unit
In ,
Since is isosceles hence point lies on perpendicular bisector of
Hence, the coordinate will be in first quadrant. By symmetry, all possible coordinates of are
