Consider the tri<strong>an</strong>gle formed by these 3 points: z1, z3 <strong>an</strong>d z3. If z1 <strong>is</strong><br />
one vertex, then z2 <strong>is</strong> obtained by rotating the position vector of z1<br />
by 2π/3 in <strong>an</strong>ti-clockw<strong>is</strong>e sense. Likew<strong>is</strong>e, z3 <strong>is</strong> obtained by rotating<br />
the position vector of z2 by the same amount. Hence, z1, z2 <strong>an</strong>d<br />
z3 are the vertices of <strong>an</strong> equilateral tri<strong>an</strong>gle inscribed on the unit<br />
circle: |z| = <strong>1.</strong><br />
