The center of gravity is the intersection of the center line and the center is the intersection of the bisector (or the center of the inscribed circle).

The epicenter is the intersection of the middle vertical lines (or the center of the circumscribed circle), and the vertical center is the intersection of the high lines.

These are called the four centers of a triangle.

There is also a center called paracentric: the intersection of the bisectors of the outer corners (there are three), (or the center of the tangent circle)

Only a regular triangle has a center. At this time, the center of gravity, inner heart, outer heart, hanging heart and four hearts are integrated.
