Andrew is using vector v to draw a copy of Triangle ABC. Complete the explanation of his error.
He drew vectors from A to A' and from B to B' that were (select) the same length as vector v. The correct vectors should each point _ units (select) and _ units (select)

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.
