Aline connecting a vertex of a scalene triangle with the midpoint of the opposite side is the
a. median.
b. bisector of the angle at the vertex.
c. altitude.
d. perpendicular bisector of the side.

The answer to the question above is letter "A. median". This is the line that connects the vertex of a triangle to the midpoint of the opposite side. Other choices are also line from the vertex of the triangle extending towards the opposite side. However, they do not necessarily be at the midpoint of the opposite side.
