Line

You can find the **Segment**on a Cartesian Plane**length**of a line

**segment**by counting the units that the line

**segment**covers. Countingthe units on a graph is like counting the number of blocks traveledbetween your house and your friend's house. Count the number ofunits between the two end points.

Simply so, what is the measure of a line segment?

A **line segment** is just part of a **line**. Ifyou want to **measure** the length of a **line segment**, putthe endpoint of the **segment** on the zero mark of the ruler.Then see where it ends. In inches round to the nearest ¼,and in centimeters **measure** to the nearestcentimeter.

**How to measure an angle with a protractor:**

- Place the midpoint of the protractor on the VERTEX of theangle.
- Line up one side of the angle with the zero line of theprotractor (where you see the number 0).
- Read the degrees where the other side crosses the numberscale.

Accordingly, what is the length of line segment jk?

Answer: The **length of line segment JK** is2√13.

On the flat coordinate plane, there are two axes, thevertical y-axis and the horizontal x-axis. The **origin** is thepoint where they intersect. This point has the coordinates 0,0 andis usually labelled with the letter O.
