Notice how AP = AT + TP and AP = AB + BP

Since AB = TP (given), this means

AP = AT + TP and AP = AB + BP

becomes

AP = AT + TP and AP = TP + BP

AP = AT + TP and AP = BP + TP

So this means that

AP = AT + TP

BP + TP = AT + TP

BP + TP - TP = AT + TP - TP

BP = AT

AT = BP

which proves that segment AT is congruent to segment BP
