Question

which is shown, an altitude, a median, or neither? is shown. an altitude a median neither

Explanation:

Step1: Recall Definitions

• Altitude: A segment from a vertex perpendicular to the opposite side (or its extension).
• Median: A segment from a vertex to the midpoint of the opposite side.

Step2: Analyze the Diagram

The segment from \( A \) to \( BC \) has a right - angle symbol, meaning it is perpendicular to \( BC \). For a median, we would need it to connect to the midpoint, but here the key feature is the right angle (perpendicularity), which matches the definition of an altitude.

Answer:

An altitude
