Since angles G and T are right angles, so the segments DG and CT are parallel.

That means angles C and D are corresponding angles, therefore they are congruent.

Also, angle A is common to both triangles ADG and ACT.

Since we have two pairs of congruent angles between the triangles, they are similar by case AA.

Correct option: First one.
