We are asked to perform a 180° rotation about the origin on the given triangle.

First, let us identify the coordinates of the original triangle.

Recall that the rule for 180° rotation about the origin is given by


(x,y)\rightarrow(-x,-y)

Let us apply the above rule to the origin coordinates of the triangle.


\begin{gathered} (-2,-1)\rightarrow(2,1) \\ (-5,3)\rightarrow(5,-3) \\ (-3,4)\rightarrow(3,-4) \end{gathered}

Finally, let us draw the new triangle.
