Teorema Lester

Teorema Lester dalam geometri menyatakan bahwa untuk segitiga sembarang, terdapat dua buah titik Fermat, titik pusat dari lingkaran sembilan titik, dan titik pusat dari lingkaran luar yang terletak pada lingkran yang sama. Teorema ini dinamai dari June Lester, yang menerbitkannya pada tahun 1997,[1] dan titik-titik tersebut yang disebut lingkaran Lester dinamai oleh Clark Kimberling.[2] Lester membuktikan hasil teorema tersebut dengan menggunakan sifat-sifat bilangan kompleks. Sementara itu, beberapa penulis lain membuktikannya dengan menggunakan bukti-bukti elementer[3][4][5][6], bukti menggunakan aritmetika vektor,[7] dan bukti terkomputerisasi.[8]
