Hey can someone help me measure these angles

A is acute and B is obtuse.

Step-by-step explanation:

This is because any angle less then 90 is acute and any angle over 90 degreee is obtuse.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
