文[1]提出了三角形的一个“性质”并给出了证明,文[2]又给出了“性质1”并且也给出了证明.受它们的启发,本文也将有关性质进一步探究推广.设P是△ABC所在平面内任意一点(不在△ABC三条边所在直线上),S△ABC表示△ABC的面积,λ1=S△PBCS△ABC,λ2=S△PCAS△ABC,λ3=S△PABS△ABC In [1], we propose a “nature” of the triangle and give proof. The article [2] also gives “nature 1” and also gives the proof. Inspired by them, this article will also further explore the nature of the extension. Let P be any point in the plane of △ABC (not on the line where △ABC is located on three sides), SΔABC represents the area of ​​△ABC, λ1=SΔPBCSΔABC, λ2=SΔPCASΔABC, λ3=S △PABS△ABC
