Question Analysis

The main focus is to identify the altitude among the given line - segments in the triangle by applying the definition of an altitude and analyzing the visual cues.

 

Key Concept Explanation

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

 

Step - by - Step Solution

1. Analyze ZR:

ZR is a median as R is the mid - point of WX. It does not meet the criteria of an altitude as it is not perpendicular to the opposite side from Z.

 

2. Analyze RT:

RT is a perpendicular bisector as it is perpendicular to WX and R is the mid - point of WX. It is not an altitude as it does not start from a vertex to be perpendicular to the opposite side.

 

3. Analyze WY:

WY is an angle bisector as indicated by the arc marks. It is not an altitude as it is not perpendicular to an opposite side from W.

 

4. Analyze XS:

XS has a right - angle mark,...
