A question about junior high school mathematics: what is the integral of three lines; What can be introduced according to the trinity principle?
The combination of three lines means that in isosceles triangle and equilateral triangle, the midline, height and angular bisector of the triangle are the same line.
Application: In isosceles triangle and equilateral triangle, knowing that one line can lead to the other two lines. Through the combination of three lines, it is also concluded that the triangle is an isosceles triangle.
