The magnitude <math>|z|</math> of a complex number <math>z</math> is equal to the number's distance from the origin. The condition <math>|z|=2</math> therefore says that <math>z</math>'s distance from the origin should be 2, i.e. the condition gives a circle of radius 2 and centre at the origin.

The magnitude z of a complex number z is equal to the number's distance from the origin. The condition z=2 therefore says that z's distance from the origin should be 2, i.e. the condition gives a circle of radius 2 and centre at the origin.
