Geometric Construction of Complex Division z1 / z2 = z3

This GeoGebra example demonstrates the geometric meaning of complex division on the complex plane, showing how the quotient z3 relates to dividend z1 and divisor z2 through modulus division and argument subtraction. Core concepts include complex numbers, complex division, modulus and argument, complex plane geometry, and rotational-scaling transformations. Construction uses GeoGebra commands Segment and Angle, with objects z_1, a, α, z_2, z_3, b, c and text label text1 to visualize segments and angles between complex numbers. Suitable for high school complex number electives and undergraduate algebra introductions, ideal for classroom demonstration and inquiry-based learning.
