Which is used to draw line segments and to measure their lengths ?

Options

A. Set squares
B. Protractor
C. Ruler
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Line Segments**: A line segment is a part of a line that has two endpoints. For example, let’s label the endpoints of our line segment as point A and point B.

2. **Drawing the Line Segment**: To draw a line segment, you can use a ruler or a straightedge. Place the ruler on your paper and mark the starting point (A) and the ending point (B). Then, draw a straight line connecting these two points.

3. **Measuring the Length**: To measure the length of the line segment AB, you will use a scale (or ruler). Place the scale along the line segment such that one end of the scale is at point A and the other end is at point B.

4. **Reading the Measurement**: Look at the scale to see the measurement at point B. This will give you the length of the line segment AB.

5. **Conclusion**: Therefore, a scale is used to both draw line segments and measure their lengths.
