Which of the following is true about an isosceles trapezoid? the bases are not congruent. the diagonals are not congruent. the diagonals bisect each other. the diagonals are congruent.

The diagonals are congruent.

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.
