Question

look at the diagram. which term describes ac? median angle bisector altitude none of these

Explanation:

• A median of a triangle is a line segment joining a vertex to the mid - point of the opposite side. There is no indication that \(C\) is the mid - point of \(BD\), so \(AC\) is not a median.
• An angle bisector is a line segment that divides an angle into two equal parts. There is no information suggesting that \(AC\) bisects \(\angle BAD\), so \(AC\) is not an angle bisector.
• An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side. Here, \(AC\perp BD\) (as indicated by the right - angle symbol), so \(AC\) is an altitude.

Answer:

altitude
