Question 60882
Let's say that the two points have the coordinates: (x1, y1) and (x2, y2), you can find the didtance between these two points using the distance formula:
{{{d = sqrt((x2-x1)^2 + (y2-y1)^2)}}}

This is an application of the Pythagorean theorem applied to finding the length of the hypotenuse of a right triangle when you know the length of the two legs.

In your problem, the lengths of the two legs are: {x2-x1) and (y2-y1).
