It is established in globe map, not in my map. My established cities are different. I've posted an image of my map already. Chose cities have green or yellow color in upper image then I can do it.
Either suggest cities from flat map, or shut up.
The point he is making is that it doesn't matter.
It is literally impossible to draw these cities with the same distances on a flat map.
It isn't a case of your particular map disagreeing.
It is a case of it being mathematically impossible to map a curved surface like Earth onto a flat surface.
Any attempt to do so will have distortion and result in the distances changing.
With the accuracy of known locations of these cities the distances are known accurately enough to cause problems even for Europe.
Yes, you can make a map and say the distances are only known to within 40 000 km and use that to pretend they match.
But you will never be able to make a map to the same accuracy and have them match.
This means it is IMPOSSIBLE for accurately known distances to match on a RE and FE.
Saying you don't know the distance on a FE accurately enough to see if they match is not a valid rebuttal.
Yes, depending on the location you pick for each city, the distance may vary, but using the same locations from each city that excuse doesn't work.
The easiest way to show they don't work is what he has already done.
If you use 3 cities, you can construct a triangle. There is only one option for this triangle.
Then if you add another city you can construct a triangle from either set of the locations. (technically there are 2 options for these however it is typically fairly obvious which one is correct. Picking the other one below won't help).
The problem is it doesn't match for RE and FE.
Again, using the 4 cities he has chosen (Ankara, Dublin, Helsinki & Lisbon) you get the following pairs of distances:
| City | City | Distance/km |
| Ankara | Dublin | 3283 |
| Ankara | Helsinki | 2318 |
| Ankara | Lisbon | 3581 |
| Dublin | Helsinki | 2024 |
| Dublin | Lisbon | 1640 |
| Helsinki | Lisbon | 3360 |
From that we can construct our triangles.
Our base triangle will be Ankara, Dublin, Helsinki.
Then we will make a triangle to Lisbon from all 3 locations.
If we assume Earth is flat, and use the RE distances we get this:

And a zoomed in version of "Lisbon":

Notice that instead of being a single point we end up with 3 points.
These form a triangle with distances of 36, 51 and 74 km.
Again, this is not an issue with your specific map, or any specific FE map. It is a problem with trying to take distances from a RE and applying them to a FE map. They simply cannot work.
If you wish to disagree then show us a map where these distances match.
i.e. show us a map where you have the following distances:
| City | City | Distance/km |
| Ankara | Dublin | 3283 |
| Ankara | Helsinki | 2318 |
| Ankara | Lisbon | 3581 |
| Dublin | Helsinki | 2024 |
| Dublin | Lisbon | 1640 |
| Helsinki | Lisbon | 3360 |
If you can't produce such a map then don't claim that FE distances can match RE distances.
