Which glide reflection describes the mapping triangle abc to def

The correct option is A.

Step-by-step explanation:

The correct option is A.

If u notice the second transformation it would shift  triangle ABC 3 units to the left and reflect it across x = 4 so this will not map ABC into DEF.

If u notice first transformation it will shift triangle ABC 7 units down and reflect it across x=4 so this will map ABC into DEF.

Thus option A is correct

60: 45 =12: 9 =4: 3 so the answer is 4: 3
