Abstract
SummaryEuler’s inequality in Euclidean geometry is a famous result relating the circumradius and inradius of a triangle. We provide a new proof of this result using elementary ideas about area and isosceles triangles.MSC: 51M04 Additional informationNotes on contributorsNam Gu HeoNAM GU HEO (MR Author ID: 1106949) studied mathematics education and received an Ed.D. from the Korea National University of Education. Currently, he is a professor at Sunchon National University, Korea.
