Look at △ TXA and △ T'X'A' shown below.

Which of these can be used to prove that △ TXA ~ △ T'X'A'?


△ TXA is rotated 270° counterclockwise about the origin and then dilated by a scale factor of 2 about A the origin to obtain △ T'X'A'.

△ TXA is rotated 270° counterclockwise about the origin and then dilated by a scale factor of 1/2 about the origin to obtain △ T'X'A'.

△ TXA is rotated 90° counterclockwise about the origin and then dilated by a scale factor of 1/2 about the origin to obtain △ T'X'A'.

△ TXA is rotated 90° counterclockwise about the origin and then dilated by a scale factor of 2 about D. the origin to obtain △ T'X'A'.
