(2,1) (4,2) (3,5) rotated 180 degrees clockwise

To rotate a point (x, y) 180 degrees clockwise, we can switch the signs of both x and y coordinates.

For the first point (2, 1), the rotated point will be (-2, -1).

For the second point (4, 2), the rotated point will be (-4, -2).

For the third point (3, 5), the rotated point will be (-3, -5).

So the points (2, 1), (4, 2), and (3, 5) rotated 180 degrees clockwise are (-2, -1), (-4, -2), and (-3, -5).
