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.
[tex]A(3,0),B(1,4),C(5,3)[/tex]Thus, the new coordinates will be as follows.
[tex]A^{\prime}(-3,0),B^{\prime}(-1,-4),C^{\prime}(-5,-3)[/tex]Plot the coordinates in a Cartesian coordinate system and then connect the points.
