To find the coordinates of point C' after rotating point C(4, 4) by 180° clockwise around the origin, you can use the following rule for 180° rotation:
If \( C(x, y) \) is a point, then after a 180° rotation around the origin, the new coordinates \( C'(x', y') \) can be calculated as:
\[ C'(x', y') = (-x, -y) \]
For point C(4, 4):
\[ C' = (-4, -4) \]
Thus, the coordinates of point C' are:
C' = (-4, -4)
