Question

in the square pyramid shown below, which lines are parallel? fi and gh ij and fi hi and fg gj and hi

Explanation:

Step1: Recall parallel - line definition

In 3 - D geometry, parallel lines lie in the same plane and do not intersect.

Step2: Analyze the square - pyramid

In a square - pyramid, the base is a square. The opposite sides of the square base are parallel. In the given square - pyramid, the base is square \(GHIJ\). So, \(\overrightarrow{GJ}\) and \(\overrightarrow{HI}\) are parallel as they are opposite sides of the square base.

Answer:

\(\overrightarrow{GJ}\) and \(\overrightarrow{HI}\)
