(40 Points, Please Explain your answer.) In quadrilateral ABCD, the diagonals intersect at point T. Jasmine has used the Alternate Interior Angles Theorem to show that angle DAC is congruent to angle BCA and that angle ADB is congruent to angle CBD.

Which of the following can Jasmine use to prove that triangle ATD is congruent to triangle CTB?

AB ≅ DC
AC ≅ DB
DA ≅ BC
AC ≅ AC
