Addition of Two Complex Numbers (with Animation)

① This GeoGebra example dynamically demonstrates the geometric meaning of adding two complex numbers, applying the parallelogram law of vector addition on the complex plane. ② The core mathematical concepts are complex number addition, vector representation on the complex plane, and the geometric construction of vector sums. ③ Construction highlights: the Intersect command finds intersection points, Segment creates line segments, and Vector constructs vectors; objects include points A and B, vectors f and g, resulting vectors h, i, j, along with text1 and sliders t and u for animation control. ④ Suitable for high school or early college students learning complex numbers and vector geometry, and for teachers to visually explain the geometric essence of complex addition in class.
