Given the coordinates of the trapezoid TANS as

The coordinates of the image T'A'N'S' is

From the coordinates of the image given above, it is observed that the transformation rule is

The transformation rule stated above is that of 90 degrees clockwise rotation, and rotation of figures produce congruent figures
Hence, the answer to the question is;
Yes, they are congruent because the image is a rotation of the pre-image and rotation produce congruent figures
