1. **Problem Statement:** Determine the number of line segments shown in the described drawing. 2. **Understanding the Drawing:** - There is a main diagonal line with arrows on both ends, indicating it is a line (infinite in both directions). - Four equally spaced points lie on this line. - Between the second and third points, there is a small rotated square. - The square has 4 line segments forming its perimeter. - Additionally, there are 2 line segments connecting the square to the main line (one on each side). 3. **Counting Line Segments:** - The main line itself is infinite, so it is not a line segment. - The points on the main line create segments between them: - Between point 1 and 2: 1 segment - Between point 2 and 3: 1 segment - Between point 3 and 4: 1 segment Total on main line: 3 segments - The square has 4 line segments (its sides). - The two connecting segments from the square to the main line add 2 more segments. 4. **Total Number of Line Segments:** $$3 + 4 + 2 = 9$$ **Final answer:** There are 9 line segments in the drawing.
