Circumradius equals the radius of the circle that touches the vertices of the polygon/circle in which the polygon can be inscribed.
In triangle ABC, R(b+c)=a√bc, where R is the circumradius of the triangle. Then the triangle is Aisosceles but not right Bright but not isosceles Cright isosceles DequilateralSubmit If H is the orthocentre of the triangle ABC, R = circumradius and P=AH+BH+CH, then Ap=2(R+r...
