I hope this Helps!

Answer 2

D) dilate ΔABC by a scale factor of 1/2

Explanation:

Inverse of anything means the reverse or opposite of it.

Here, its given -

dilate ΔABC by a scale factor of 2.

Means double the scale factor. So, its inverse will be half the scale factor.

D: dilate ΔABC by a scale factor of 1/2.

Its like we have been given to multiply something by 2, but we have to apply inverse of it. That will be divide that thing by 2.
