A number in the form a + bi, where i^2 = -1.
It shows complex numbers as points (x, y) on a plane.
The conjugate is a - bi, reversing the imaginary part.
It's the distance from the origin, |z| = √(x² + y²).
It results in a 90° anticlockwise rotation around the origin.
It indicates a line with a fixed angle on the complex plane.
z = r(cos θ + i sin θ), where r is the modulus.
Use vector addition and the parallelogram rule.
