WebJun 4, 2024 · For an obtuse triangle, the circumcenter is outside the triangle. Inscribed circles. When a circle inscribes a triangle, the triangle is outside of the circle and the circle touches the sides of the triangle at one point on each side. The sides of the triangle are tangent to the circle. WebNow we can define r as a function of θ via the relation r(θ) = AI(θ) P(θ) = sin(2θ) 4(1 + cos(θ)) Now you can find when r ′ (θ) = 0 and optimize r(θ) Let the unknown triangle's …
