Triangle ABC Median: Identify the Connecting Line and Its Base Side

A median of a triangle is a line segment that connects a vertex to the midpoint of the opposite side. In triangle $\triangle ABC$, we need to identify such a median from the diagram provided.

Step 1: Observe the diagram to identify the midpoint of each side.

Step 2: It is given that point $E$ is located on side $AC$. If $E$ is the midpoint of $AC$, then any line from a vertex to point $E$ would be a median.

Step 3: Check line segment $BE$. This line runs from vertex $B$ to point $E$.

Step 4: Since $E$ is labeled as the midpoint of $AC$, line $BE$ is the median of $\triangle ABC$ drawn to side $AC$.

Therefore, the median of the triangle is $BE$ for $AC$.
