Question

Which of the flags has been rotated 180 degrees about the origin ( point) A ? The directions continue in the picture

Answer 1

Given:

The image would be

The rule for 180^0 rotation about the origin is given as

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

The coordinate of the pre-image is

$\begin{gathered} B=(3,3) \\ C=(5,5) \\ D=(7,3) \\ E=(5,1) \end{gathered}$

The coordinate of the image using the 180^0 rotation about the origin is

$undefined$
