Pls i need help i’ll give brainliest

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Ibelieve the shape kept its shape as it rotated. the angle would stay the same. if im wrong notify me≤⊃
