To obtain the 180° rotation, obtain the (-x,-y) coordinates of the given (x,y) coordinates.
The given coordinates of the points are as follows.
![A(3,0),B(1,4),C(5,3)](https://img.qammunity.org/2023/formulas/mathematics/college/smqxhfbunjt7po00exfru3ba03xqsthjes.png)
Thus, the new coordinates will be as follows.
![A^(\prime)(-3,0),B^(\prime)(-1,-4),C^(\prime)(-5,-3)](https://img.qammunity.org/2023/formulas/mathematics/college/lmvwvp387a537lcodusfjc1exl7ofosro1.png)
Plot the coordinates in a Cartesian coordinate system and then connect the points.
