The Incenter is located on top of point X. I found the Incenter by taking the perpendicular bisector of each line and they landed on point X (I)

Centroid

The centroid is indicated by point M. Point M was found by finding the Angle bisector of each line.

Circumcenter

The circumcenter is shown as point C or the Green point. The first step to finding the circumcenter was to add a circle on the three points of a triangle, after that I would find the midpoint of the circle , and use the lines to connect them with the point C

Orthocenter

I find the orthocenter by taking a point and connecting it to an opposite line using a vertex. I did this for all 3 point and they came together at 1 point which is the orthocenter.
