so if similar means that the points are in the same orientation reletive to each other (exg point 1 is to the right of point 2 and both are above points 3 and 4)


so rotations and reflections change the orientation reletive to each other so choicesย  A and D are out

Dialations and translations just move the whole thing, yet it stays the same points reletive to each other so the answers are B and C

Sorry if it is wrong, don't know this the best
I think the answer is B and C

Answer:

B.Parallelogram JKLM is dilated by a scale factor of 6 and then translated 2 units down to form parallelogram J๊žŒ๊žŒK๊žŒ๊žŒL๊žŒ๊žŒM๊žŒ๊žŒ; and C.Parallelogram JKLM is translated 6 units up and then dilated by a scale factor of 10 to form parallelogram J๊žŒ๊žŒK๊žŒ๊žŒL๊žŒ๊žŒM๊žŒ๊žŒ.

Step-by-step explanation:

Some transformations are called rigid transformations. ย This is because they preserve congruence. ย These are translations, rotations and reflections. ย Any combination of these three transformations will result in congruent figures.

This means if we want similar and not congruent figures, the figure must be dilated. ย The only two choices that mention dilations are B and C.
