Answer:
The lengths of DF and HI
Step-by-step explanation:
SSS
This means Side Side Side
So to prove this triangle is similar we have to use only true information about the sides.
We can already cross off the second and last answer choices because they are talking about angles.
The first answer choice is about the sides but first we have to determine if its true or not.
Side DF is on the left opposite of angle G
HI is also on the left, opposite of angle I
We can assume those sides are the same but to really know we can check if the other sides match up
We know this constriction has a scale factor of: 1.66666667
If you divide 3.5 by our scale factor you get 2.1
If you divide 5 by our scale factor you get 3
This proves that DG and HJ and FG and IJ would be the matching constricted side
This means that DF and HI would be matching as well making the first answer choice correct.
I hope this helps, don't be afraid to reach out with any further questions! Have a nice day!
