Add to ORKGLet ABC be a triangle. Let A'A'', B'B'', and C'C'' be tangents to the incircle of ABC and parallel to BC, AC, and AB, respectively, so that A'', B' are on AB, B'', C' are on BC, and C'', A' are on CA . Let R be the circumradius of ABC and R_A, R_B, and R_C be the circumradii of AA'A'', BB'B'', and CC'C'', respectively. Then R= R_A+R_B+R_CComponente Curricular::Ensino Médio::MatemáticaComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemátic
