Joshua is constructing a triangle with a circle inscribed in it. Each vertex of the triangle will have a line passing through it bisecting the angle. No matter where he places the third vertex, the following conditions will be true: • Each line will always bisect its corresponding vertex angle. • The three lines will always intersect at the center of the circle. • The circle will always be inscribed in the triangle. Which type of center​ (a)   exists where the three lines intersect?

• INCENTER

• CENTROID

• CIRCUMCENTER

• MIDPOINT
