Let \( z_{1} \& z_{2} \) be non zero complex numbers satisfying the equation, \( z_{1}^{2}-2 z_{1} z_{2}+2 z_{2}^{2}=0 \). The geometrical nature of the triangle whose vertices are the origin and the points representing \( z_{1} \& z_{2} \) is :
\( \mathrm{P} \)
(A) an isosceles right angled triangle
(B) a right angled triangle which is not isosceles
W
(C) an equilateral triangle
(D) an isosceles triangle which is not right angled.
