In a quadrilateral ABCD, the diagonals intersect at point T. Heather has used the Alternate Interior Angles Theorem to show that angle ABD is congruent to angle CDB and that angle BAC is congruent to DCA. Which of the following can Heather use prove that segment DT is equal to segment TB?

AB ≅ DC
AC ≅ DB
DA ≅ BC
AC ≅ AC

B.

Step-by-step explanation:

A

Step-by-step explanation:

There are two triangles that can be formed without overlapping, ATB and CTD. With the alternate interior angles, there are two congruent angles for each of the triangles. If AB is congruent to DC that would be the side in between the two angles making the triangles in the quadrilateral congruent by ASA. Then, DT will be congruent to TB because of CPCTC.
