incenter
Inscribed circle's center
The incenter is the point where the three angle bisectors of a triangle meet.
It serves as the center of the triangle's inscribed circle—the largest circle that fits inside the triangle, touching all three sides.
Unlike the centroid or circumcenter, the incenter always lies inside the triangle regardless of its shape.
