Best ResponseYou've already chosen the best response.0Angle ATB is congruent to Angle CTB. Angle ADT is congruent to Angle ATB. Side AB is equal to the diagonal DB of the quadrilateral. Side BC is equal to the diagonal AC of the quadrilateral.

Best ResponseYou've already chosen the best response.0Seems like a square. So all the angles are 90 degrees?

Best ResponseYou've already chosen the best response.5I am thinking A as well, although I'm just reading the question again because it feels like A is the only logical answer. lol Well, AB = BC could also be a rhombus or a kite.

Best ResponseYou've already chosen the best response.5The first choice works, because the sides bisect each other and then we can show that the right triangles are congruent, thus the corresponding parts are congruent. The second choice, if those two were the same angle, then there'd be an issue with point D being on top of T (like, it'd be the exact same angle) The last two don't really help us prove anything unless we introduce more information.
