Answer:
A. 30 degrees
Step-by-step explanation:
There are four types of transformations and there are reflection, rotation, dilation, and translation.
Reflection, rotation, and translation are rigid transformations, that is, the preimage and image do not change in size or shape. It also means that the preimage and image will be congruent.
So if triangle BCD is rotated 80 degrees clockwise about the origin to form triangle KLM, and m
