# How do you find the length of a segment in geometry?

**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.

Moreover, 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.

Likewise, how do you measure angles? **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.

Secondly, what is the length of line segment jk?

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

What is the origin of a line segment?

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.
