Answer:
Very Simple!
Explanation:
Just use the distance formula!
(I'm in a math class right now, so I have to keep it brief)
Distance Formula, example:
![AB=\sqrt{(x_(1)-x_(2))^(2)+(y_(1)-y_(2))^(2) }](https://img.qammunity.org/2021/formulas/mathematics/college/oe6g5kcjumr7ustvpx3jdm7ubrbd62iu1j.png)
Just input the x and y values from A and B into here, and then that's it!
Hope this helps!
Happy Geometry!
