What 3 pieces of evidence did wegener use to support his theory?

The three pieces of evidence that Alfred Wegener used to support his theory that the Earth's continents were once joined together as one large continent, called Pangaea, were:
-Pieces of fossil that were found in Africa and South America are very similar, almost identical, and it would have been difficult for them to stay in tact, if they had travelled via the current.
-The rock formations and the mountain chains that are found in both Africa and South America are very similar, once again, almost identical, and this is something that could have struggled to have occurred, if the earth didn't used to be one continent.
-The coastline of Africa and South America are very similar to that of a puzzle (they were when Wegener studied them, but they have changed due to erosion), and this helped him to confirm his theory.

Hope this helps :)
