Choose the correct answer from the given four options. One vertex of the equilateral triangle with centroid at the origin and one side as
x + y – 2 = 0 is
[Hint: Let ABC be the equilateral triangle with vertex A (h, k) and let D (α,β ) be the point on BC. Then 2α+h3=0=2β+k3. Also α+β−2=0 and (k−0h−0)×(−1)=−1]
