WebABC is a triangle that is inscribed in a circle. The angle bisectors of A, B, C meet the circle in D, E, F, respectively. Show that AD is perpendicular to EF. We'll concentrate on ΔFIM. By a theorem of the inscribed angles, ∠IFM = ∠CFE = ∠CBE = ∠B/2. By a the theorem of the secant angles (or with the help of the Exterior Angle Theorem ), WebABC is a triangle in which ∠A= 72∘, the internal bisectors of angles B and C meet in O. Find the magnitude of ∠BOC. Solution In ΔABC,∠A= 72∘ and bisectors of ∠B and ∠ C meet at O. Now ∠B+∠C = 180∘−72∘ =108∘ ∵ OB and OC are the bisectors of ∠B and ∠C respectively ∴ ∠OBC+∠OCB= 1 2(∠B+∠C) = 1 2×108∘ =54∘ But in ΔOBC, ∴ ∠OBC+∠OCB+∠BOC= 180∘
