Question

name the following segment or point.
given:
l, m, n are midpoints
altitude to \overline{ab}
segment cn
segment cr
segment bl

Explanation:

Step1: Recall the definition of altitude

An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side.

Step2: Analyze each segment

• Segment \(CN\): \(N\) is a mid - point. A segment from a vertex to the mid - point of the opposite side is a median, not an altitude.
• Segment \(CR\): \(CR\perp AB\) (as indicated by the right - angle symbol at \(R\)). Since \(CR\) is a segment from vertex \(C\) perpendicular to the line containing \(AB\), it is the altitude to \(\overline{AB}\).
• Segment \(BL\): It is not from the vertex \(C\) to the line \(AB\).

Answer:

segment \(CR\)
