Britain is an island on which England, Wales and Scotland are on. Edward I was King of England. He invaded both Wales and Scotland, so he invaded other parts of Britain, but it would be incorrect to say he invaded Britain, as he was from England and was England's King, succeeding his father, Henry III.
Wales and Scotland both have a border with England.
England and Wales are both integral parts of the United Kingdom.
they both invaded at the same time because they both had a claim on the throne (after Edward's death).
Scotland and Wales both border England.
The M4 and M48 both link England and Wales. The M48 is the old M4 which existed before the new Severn bridge crossing was built. The M48 leaves the M4 in England and rejoins its in Wales.
Great Britain is comprised of England, Scotland and Wales, both of which have a border with England.
If you mean England, then it borders Wales and Scotland. If you mean Great Britain and Northern Ireland, then it borders the Republic of Ireland/Eire. Both border France via the English Channel.
Wales is a part of the UK and as of such is not a sovereign country. Because of this Wales on its own doesn't have any borders. The UK as a whole shares borders with the Republic of Ireland. Wales is next to England but as they are both part of Britain and therefore the same country this isn't an official border.
Both. The Severn rises near Llanidloes, Powys, in the Cambrian Mountains of mid Wales. It then flows across the border into England and through Shropshire, Worcestershire and Gloucestershire, before flowing through an estuary into the Bristol Channel, between England and Wales.
Both Wales and England are part of the United Kingdom, but Wales is not part of England. The capital of Wales is Cardiff (or Caerdydd, in Welsh). The capital of England, and also capital of the UK, is London.
The biggest difference was that in1535-1542the kingdoms of wales and england were united by henry viii.
