Resultados de la Olimpiada Iberoamericana de Matemática

==============================================

Christian Altamirano Modesto 41 puntos Medalla de Plata

Christian Suyo Burga 35 puntos Medalla de Plata

Kevin Aza Valencia 30 puntos Medalla de Bronce

Jimmy Espinoza Palacios 29 puntos Medalla de Bronce

Cabe mencionar los cortes de puntajesde medallas, que por cierto estuvieron bastante altos, sobre todo el de oro.

Medalla de oro 42 puntos, es decir puntaje perfecto, solo se dieron 5 medallas de oro.

Medalla de plata 31 puntos
Medalla de bronce 21 puntos


PARABENS PELA MEDALHAS DE PRATA E BRONZE VOCES SÃO A DEMOSTRAÇAO QUE COM DISCIPLINA,ESTUDO,PERSEVERANCIA SE VÃO LONGE,A CONTINUAR TREINANDO E ESTUDANDO HOJE PRATA E BRONZE,AMANHA A CONQUISTAR AS MEDALHAS DE OURO ,FELICIDADES.

Journal of Classical GEOMETRY

The Journal of Classical Geometry is a refereed electronic journal devoted to problems of classical Euclidean geometry. It is addressed for school teachers, advanced high-school students, and everyone with an interest in classical geometry. The journal values synthetic arguments, intelligibility and illustration.

The journal focuses on new results in triangle geometry, geometry of conics, non-Euclidean and elementary combinatorial geometry. New synthetic proofs for known facts and interesting unsolved problems are also welcome.
