∠abc is a 40∘ angle. point a is at (7, 1) point b is at (3, 2) point c is at (8, -1) if ∠abc is rotated 180∘ about the origin, what are the new points on the image and what is the new angle degree measurement?

The new points would be (-7, -1), (-3, -2) and (-8, 1). The angle would not change

Step-by-step explanation:

When you rotate points by 180 degrees, you simply change the sign on the ordered pairs. This will give you the new points.

Also, spinning the points will not change the angle between them. Therefore it stays the same.
