Question

If \( |z_1|=|z_2|=|z_3|=1 \) and \( z_1+z_2+z_3=0 \), then the area of the triangle whose vertices are \( z_1,z_2,z_3 \) is:

• A. \( \frac{3\sqrt{3}}{4} \)
• B. \( \frac{\sqrt{3}}{4} \)
• C. \( 1 \)
• D. \( 2 \)

Hint:

If unit complex numbers sum to zero: \begin{itemize} \item They form cube roots of unity. \item Triangle is equilateral. \end{itemize}
