Question

1. points d, e, and f are non - collinear. how many lines can be drawn that pass through f and are perpendicular to (overline{de})? use a diagram to illustrate your answer.

Explanation:

Step1: Recall geometric principle

In a plane, given a line $\overline{DE}$ and a point $F$ not on the line, there is exactly one line that can be drawn through the point $F$ and is perpendicular to the line $\overline{DE}$. This is a fundamental property of perpendicular lines in Euclidean geometry.
