Question

what is the name of this figure?

Explanation:

A line segment is a part of a line that is bounded by two distinct endpoints. In the given figure, there are two endpoints \( D \) and \( E \), and the figure is a straight path between these two points, so it is a line segment. We can name it using the two endpoints, so it's segment \( DE \) (or \( \overline{DE} \)).

Answer:

Segment \( DE \) (or Line segment \( DE \), or \( \overline{DE} \))
