Which can the medians of a triangle intersect- 1. inside the triangle 2. on the triangle 3 outside the triangle

  1.  inside the triangle

Step-by-step explanation:

Except for their endpoints, all the points of every median are inside the triangle. The endpoints of each median are different from those of any other, so there will be no point of intersection there.

The medians can only intersect inside the triangle.
