Question

On the graph, △DEF was transformed to create △DGH.



Which transformations show that △DEF is similar to △DGH?

A
a dilation by a scale factor of 6 and then a 180° rotation about the origin

B
a dilation by a scale factor of 6 and then a translation 6 units down and 6 units left

C
a dilation by a scale factor of 3 and then a 180° rotation about the origin

D
a dilation by a scale factor of 3 and then a translation 6 units down and 6 units left

Answer 1

Answer:

it's B

Step-by-step explanation:

by analyzing it I figured it was 100% B

Answer 2

Answer:

C. a dilation by a scale factor of 3 and then a 180 degrees rotation about the origin.

Step-by-step explanation:

G is the same point transformed as E and H is the same as point F.

Since G is now (-9,0) that was multiplied 3 times from (3,0) before it was rotated. Which would show that the answer is probably C or D.

Next, the answer looks as though it has been rotated around D or the origin by 180 degrees but we don't know that quite yet.

So check if you dilated triangle DEF by a factor of 3 then translated it down 6 units point E would now be (9,-6).

Then translate it to the left 6 units. (3, -6). That's not the same as triangle DGH.

So the answer is C.

Hope this helps! If it does brainliest would be appreciated.
