Circle o is inscribed in the given triangle
WebFirst we will construct the angle bisectors of any two angles of triangle ABC, intersecting at point D, which is the incenter of the given triangle. Now construct the perpendicular from point D to any side of triangle ABC. This intersection is point E. Then to construct the inscribed circle use center D and radius segment DE. 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 base be 2l. Draw a diagram and use Pythagoras' …
