Khatisong ena, re tla nahana ka matlotlo a ka sehloohong a polygon e tloaelehileng mabapi le li-angles tsa eona tse ka hare (ho kenyeletsoa kakaretso ea tsona), palo ea li-diagonal, bohareng ba li-circles le li-circles tse ngotsoeng. Liforomo tsa ho fumana lipalo tsa mantlha (sebaka le perimeter ea setšoantšo, radii ea li-circles) le tsona li nkuoa.
Hlokomela: re hlahlobile tlhaloso ea polygon e tloaelehileng, likarolo tsa eona, lintlha tsa sehlooho le mefuta ho.
Lintho tse tloaelehileng tsa polygon
Thepa 1
Li-angles tse ka hare ho polygon e tloaelehileng (α) li lekana 'me li ka baloa ka foromo:

Ho polygon leha e le efe e tloaelehileng, u ka ngola selikalikoe 'me u hlalose selikalikoe se pota-potileng,' me litsi tsa bona li tla lumellana, ho kenyeletsa le bohareng ba polygon ka boeona.
E le mohlala, setšoantšo se ka tlase se bontša hexagon e tloaelehileng (hexagon) e bohareng ba ntlha O.
Area (S) e entsoeng ka li-circles tsa lesale e baloa ka bolelele ba lehlakore (a) lipalo ho ea ka foromo:
Pakeng tsa radii tsa tse ngotsweng (r) le ho hlalosoa (R) selikalikoe ho na le ho itšetleha:
