Question 593661: My question is really hard and not enrolled in a standard curriculum.
Given a triangle on a complex plane which contains three vertizes , and . Find a number which is equal to incenter (a centre of inscribed circle) of triangle.
Well, I won't describe long computations but I was succesful to find the formula of the center of circumscribed circle, it is here: http://www.part.lt/img/56a97dbe7b0b5039eda438ab99b5f6cb97.jpg
Is there a source with similar expression of incenter? Answer by richard1234(5390) (Show Source):
