Best ResponseYou've already chosen the best response.0Since given is the equilateral triangle whose all the vertices are at equidistance. Let the coordinates of the third vertex be (x, y) Hence distance of (x, y) from (0, 0) = distance of (x, y) from (2, 2) therefore by distance formula we have \[(x0)^2+(y0)^2 = [x(2)]^2+(y2)^2\] \[\rightarrow x^2+y^2 = [x+2]^2+(y2)^2\] \[\rightarrow x^2+y^2 = x^2 +4 + 4x + y^2+4 4y\] \[\rightarrow 0 =8 + 4x  4y\] \[\rightarrow 4y 4x =8 \rightarrow y x =2 \] now cosider x=0 we get y0= 2 i.e. y=2 hence (x, y) = (0, 2) could be the coordinates of the third vertex.
