### How do you find the center of irregular shap?

How the center of irregular shapes I am unaware of, but for
triangles, where any one side is flat on altitude 0, the altitude
of the center is
2 x Area divided by Perimeter
That formula is used for getting the in-radius of a circle. The
center of the circle of best fit is the center of the triangle.
