Draw an obtuse angled triangle. Draw all of its medians and show their point of concurrence.


Steps of constructions.


1. Draw an obtuse angled triangle.



2. Draw a perpendicular line from each verte× to its opposite’s side bisecting the opposite’s side.



3. After constructions of a perpendicular line from each verte×, these lines intersect each other at a point O(in fig).



4. So the AD is median of ABE is median of B and CF is median of C. In addition, O is the point of concurrence.
