# Conformal Mapping

A conformal mapping is a transformation in the complex plane that preserves local angles.

Conformal mapping is a college-level concept that would be first encountered in a complex analysis course.

### Prerequisites

Complex Number: | A complex number is a number consisting of a real part and an imaginary part. A complex number is an element of the complex plane. |

Complex Plane: | The complex plane is a term for the set of all complex numbers. Just as all real numbers can be imagined as lying on a line, all complex numbers can be thought of as points in a plane. |
