Reflect Triangle ABC over the y axis, then translate 2 units right and 1 unit up.

Rotate Triangle ABC 90 degrees counterclockwise, then translate 5 units left and 1 unit up.
Reflect Trianlge ABC over the x axis, then translate 5 units left and 2 units down.
Rotate Triangle ABC 180 degrees clockwise, then translate 3 units left and 2 units down.

The final position of Triangle ABC after all these transformations would be a new position which is difficult to determine without exact measurements. The final position would be the result of a combination of reflections, rotations, and translations. It would be recommended to use graph paper or a geometry software to accurately plot and visualize the final position of the triangle after all these transformations.
