The nature of the vertical center of a triangle is the intersection of three heights, which can form many right triangles. The vertical center of acute triangle must be inside the shape, and the vertical center of obtuse triangle must be outside the shape. The vertical center of a right triangle is the right vertex. When the triangle is three heights, the three heights must intersect, and the high line is divided into triangles. The vertical center of a triangle is the center of its vertical triangle, or the center of a triangle is the vertical center of the triangle next to it.

Definition of triangle

A triangle is a closed figure composed of three line segments on the same plane but not on the same straight line. It has applications in mathematics and architecture. Ordinary triangles are divided into ordinary triangles (three sides are unequal) and isosceles triangles (isosceles triangles with unequal waist and bottom and isosceles triangles with equal waist and bottom, that is, equilateral triangles).

According to the angle, there are right triangle, acute triangle and obtuse triangle. Among them, acute triangle and obtuse triangle are collectively called oblique triangle, and the closed geometric figure obtained by connecting three line segments end to end is called triangle, which is the basic figure of geometric pattern.
