How to measure a line segment?
A line segment is measured with the help of a ruler and a pencil. Place the ruler such that ‘0’ on the ruler is at the starting point of a line segment, i.e. A. Read ruler mark at the other end B of the line segment.
The length of the line segment AB = 5 cm.
How to draw line segments?
Let us learn to draw a line segment of length 8 cm.
1. Place the ruler on a paper. Hold it down with one hand.
2. Mark a point A, with a pencil, against the ‘0’ mark on your ruler.
3. Mark point B against the 8 cm mark.
4. Join the two points, while keeping the ruler steady.
Length of AB = 8 cm.
