Question

Figure MNOP is rotated by 180 degrees about the origin in the counterclockwise direction to obtain figure M′N′O′P′:

Answer 1

Length of MN = Length of M′N′ is the correct answer. Hope it helps :))

Answer 2

The correct answer would be:
Length of MN = Length of M′N′
Because nothing changes the length of the sides when you rotate it.

Hope this helps
