is there a way to get the x and y coordinates of a specific point which has been created in order to use that information in a formula (f(x))?
The only point that has exact x and y coordinates is the initial point (A or B, etc.). All other points are created in relation to this point. If you click on this point, you will see the x & y coordinates:
You can hover the cursor over any point to get it’s length, angle, etc. from its originating point:
Theoretically, there is no reason why you’d want the exact coordinates since you can re-use the points over and over again.
So one would click on that point and then enter a formula using the options available below:
