Answer explanation

The incenter is where a circle could be drawn inside the triangle.

The circumcenter is where a circle could be drawn around the triangle.

The centroid connects the midpoints to the vertices across the triangle.

The orthocenter is where the altitudes intersect (where the vertex is drawn to the opposite side at a right angle.
