Map the triangle on the graph. Input A, B, and C.
Then, you can just flip it over the x axis. To make it simple, you can do (x,y) -> (-x, y). Map the remainder of the triangle across the x axis. If you have any questions, please comment.
The Battle of Fort Necessity (also called the Battle of the Great Meadows) took place on July 3, 1754, in what is now the mountaintop hamlet of Farmington in Fayette County, Pennsylvania. The engagement was one of the first battles of the French and Indian War and George Washington's only military surrender.
They were upset that the USA had interfered with China!
One possibility is the geographical difference and the effect it has on people. Great Britain is an Island so it can feel relatively safe (see the fate of GB in WW2 as compared to the rest of Europe) and because of this it can afford a more separatist policy. continental Europe however need a closer cooperation between the neighbours, as they share physical land borders, and only peace and a close cooperation can give the feeling of safety (for example to German neighbors, close economic Union is the best defense against a possible attach from Germany).
