To determine the coordinates of the midpoints of a line segment, get the average of the both the abscissas and ordinates. In this example, the average of the abscissas is 22 and that of the ordinates is -4. Thus, the midpoint is (22, -4).
I do not know what is congruent here, but if it is the sides that are congruent then that statement is true, but if the angles are equal then that statement is false.
