Hey André!!!
If you look what you have drawn, It is the same thing of the first part I replied, even simplier!

anyway:

- Select AB segment, use the command "modify-rotate (keep the original!)" on it, you can use any point on the segment as centre, then use "modify-copy (don't need keep the original)" select the endpoint of the segment as start point, select C point as final point. you will have a line that start from C point and that intersect with AB segment at point 3

- Use the command "modify-rotate (keep the original!)" on the segment AB, you can use any point on the segment as centre, use "modify-copy (don't keep the original)" select the endpoint of the segment as start point, select D point as final point. you will have a line that start from D point and that intersect with AB segment at point 4

Now

-Select only the snap "intersection" and check where the lines encounter AB segment at 3 and 4

- Now you know where you can find the coordinates!!!

-YOUR JOB IS DONE!

See ya!
