1.  In Triangle ABC, the circumcenter and orthocenter are collinear with vertex A. Which of the following statements must be true?

The circumcenter is located at the intersection of the perpendicular bisectors of the sides of a triangle

The orthocenter is located at the intersection of the altitudes of a triangle


But, in an equilateral triangle, the perpendicular bisectors of the sides and the altitudes are the same
