Question

look at the diagram. which term describes hj? altitude perpendicular bisector angle bisector none of these

Explanation:

An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side. In the given diagram, \( HJ \) is a segment from vertex \( H \) and is perpendicular to side \( KI \). A perpendicular bisector would bisect the side (\( KI \) here) which is not indicated. An angle bisector would split an angle at \( H \) into two equal parts which is also not shown. Since \( HJ \) is a perpendicular segment from vertex \( H \) to side \( KI \), it fits the definition of an altitude.

Answer:

altitude
