Question

identify a pair of segments that are marked perpendicular to each other on the diagram below. (diagram is not to scale.)

Explanation:

Step1: Recall Perpendicular Definition

Perpendicular segments form a \(90^\circ\) angle (right angle), marked by a right-angle symbol (the curved mark with a small square or the arc indicating a right angle).

Step2: Analyze the Diagram

• At vertex \(J\), the right-angle symbol (arc with the right - angle indicator) is between segments \(JK\) and \(JI\). So, \(\angle KJI\) is a right angle, meaning \(JK \perp JI\) (or \(JI \perp JK\)).
• Alternatively, at vertex \(H\), the right - angle symbol is between segments \(HI\) and \(HJ\), so \(HI \perp HJ\) (or \(HJ \perp HI\)). Also, the vertical segments (like \(JK\), \(LL'\) (where \(L'\) is the foot on the base), \(MM'\) (where \(M'\) is the foot on the base), \(HI\)) are perpendicular to the horizontal - like segment \(KJIH\) (the slant side? Wait, no, looking at the arrows, the vertical segments (with upward/downward arrows) and the segment \(JI\) or \(HJ\) with the right - angle marks. Wait, the key is the right - angle marks at \(J\) and \(H\). At \(J\), the two segments forming the right angle are \(JK\) and \(JI\) (since the right - angle symbol is at \(J\) between \(JK\) and \(JI\)). At \(H\), the two segments are \(HI\) and \(HJ\). Also, the vertical segments (e.g., \(JK\), \(LM\) (wait, \(L\) has a vertical segment down, \(M\) has a vertical segment down, \(HI\) is vertical)) and the segment \(JI\) (or \(HJ\)): but the right - angle marks are at \(J\) and \(H\). So a pair like \(JK\) and \(JI\) (or \(HI\) and \(HJ\)) are perpendicular.

Answer:

A pair of perpendicular segments is \(JK\) and \(JI\) (or \(HI\) and \(HJ\), or other valid pair based on the right - angle marks in the diagram, e.g., \(JK\perp JI\))
