U-Pol uguqula amakho-odinethi angunxande abe amakho-odinethi ayi-polar, kanti u-Rec uguqula amakho-odinethi ayi-polar abe amakho-odinethi angunxande.

            (1) Izihlanganisi Zesikwele Esibanzi (Rec)
            (2) Izihlanganisi ze-Polar (Pol)

Balula iyunithi ye-engele ngaphambi kokwenza izibalo.
Umphumela wesibalo sika r nesika θ kanye nesika x nesika y ngasinye sabelwe ngokuqondile kulezi zimeleli X no, Y.
Imiphumela yesibalo θ iboniswe ngokokwehlukana kuka, -180°< θ ≦ 180°.

Isibonelo 1: Ukuguqulela izihlanganisi zesikwele esibanzi (√2; √2) kuzihlanganisi ze-polar  (Iyunithi ye-engele: Deg)

(MthIO-MathO)

• (Pol)2(;)2
• r = 2; θ = 45

(LineIO)

• (Pol)2(;)2
• r = 2
  θ = 45

Isibonelo 2: Ukuguqulela izihlanganisi ze-polar (√2; 45°) kuzihlanganisi zesikwele esibanzi (Iyunithi ye-engele: Deg)

(MthIO-MathO)

• (Rec)2(;) 45
• X = 1; Y = 1
