Does the median lie wholly in the interior of the triangle?
Hello... see, median is a line which divides something into two equal parts. So, it will surely be in the interior of the triangle. And another is altitude, a straight line projected from a vertex (corner) of the triangle perpendicular (at a right angle) to the opposite side. Its centrecan be in the interior or exterior of the triangle as in a acute triangle, it is inside but in a obtuse triangle, it is outside of the triangle.
