Question

which is the line shown in the figure?
line xy
line xz
line wx
line wz

Explanation:

Step1: Recall the definition of a line

A line extends infinitely in both directions.

Step2: Analyze each option

• line \(XY\): It is a line - segment (has two endpoints \(X\) and \(Y\), does not extend infinitely in both directions).
• line \(XZ\): It has arrows on both ends, indicating it extends infinitely in both directions.
• line \(WX\): It is a line - segment (has two endpoints \(W\) and \(X\), does not extend infinitely in both directions).
• line \(WZ\): It is a line - segment (has two endpoints \(W\) and \(Z\), does not extend infinitely in both directions).

Answer:

line \(XZ\)
