Name the line segments shown in Fig. 2.25.

AB, BC, CD, DE, EA
Step 1: A line segment is a straight path with two fixed end points.
Step 2: In the figure, the points are A, B, C, D, and E. They form a closed shape (a pentagon).
Step 3: The sides of this shape are the straight pieces joining each pair of neighbouring points.
Step 4: Name each side by its end points (write only the two letters, no arrows):
Conclusion: The line segments are AB, BC, CD, DE, EA.
