I liked this website because it was easy to understand, and it has examples of both form of complex numbers. It describes rectangular form as a complex number denoted by its respective horizontal and vertical component. The horizontal component is your real number, and the vertical component is your imaginary number. Polar form is a complex number denoted by the length (magnitude, absolute value) and the angle.

Complex number forms review (article) | Khan AcademyLinks to an external site. -This website describes rectangular and polar forms. It provides formulas and it shows how to convert rectangular form to polar form and vice versa. This site also includes visuals and examples. Another we will discuss will be exponential form which uses the same system as polar form.
