Distance Formula
This is an example of how you would use the distance formula to find the distance from the points (1,1), and (1,5).[br][math]\left(1,1\right),\left(1,5\right)->\sqrt{\left(1-1\right)\begin{matrix}^2\end{matrix}+\left(5-1\right)^2}=4[/math]
What is the Distance between point (1,2) and point (-1, -2)?
Create a line segment, using the the point tools, create two points, an then join them using the line segment tool. Use the distance tool, clicking point A first, and then point B second. (The titles of the dots will appear once the distance shows up. It does not matter the order you click the points.)
