Which construction will locate the incenter of a triangle?

Question 1 options:

Construct the angle bisectors of the vertices. The incenter is their point of intersection.


Construct a ray from each vertex to the midpoint of the opposite side. The incenter is the point of intersection of the rays.


Construct the altitude from each vertex. The point of intersection of the altitudes is the incenter.


Construct the perpendicular bisectors of each side of the triangle. The incenter is their point of intersection.
