Point inside an acute triangle

Geometry Level 3

The radius of the circumcircle of the acute triangle A B C ABC is 2018 2018 .

Point P P is inside the triangle. Is it possible that A P = 2019 , B P = 2020 , C P = 2022 AP=2019, BP=2020, CP=2022 ?

No, it's not possible. Yes, it's possible.

Point P is very close to point O, the circumcenter, and intersection of the perpendicular bisectors of the sides, since the 3 distances given are virtually equal to each other, and traverse the distance from P to the circumference. If one assumes that P and O coincide, it is an ease matter to compute the triangke sides, which become 216.9, 153.4, and 190.6, with corresponding central angles of 3.08, 2.1, and 2.7, a long way from summing to 360.
