WebTheorem 28. The point where two medians of a triangle intersect is 2/3 of the way from each of the two vertices to the opposite midpoint. Theorem 29. For any triangle ABC, the three medians are concurrent. Theorem 30. Let ABC be any triangle. Let O be the circumcenter of ABC, let G be the centroid of ABC, and let H be the orthocenter of ABC. WebIn triangle ABC,R(b+c)=a bc, where R is the circumradius of the triangle. Then the triangle is? A Isosceles but not Right angled triangle B Right angled triangle but not Isosceles C Right angled isosceles D Equilateral Medium Solution Verified by Toppr Correct option is C) R(b+c)=a bc 2b+c≥ bc b+c bc ≤ 21 ∴aR≤ 21 2sinA1 ≤ 21 R= 2sinAa ∴aR= 2sinA1
