Solution
How do you rotate 270 degrees clockwise and determine the marked figure
The coordinate of the figure ABCD are
The rule for a rotation by 270° about the origin is (x,y)→(y,−x)
and the new coordinates will be
The coordinate of the new figure A¹B¹C¹D¹ are
Therefore the marked coordinate of the original figure is (-5 , 6) also point in the final figure will be (6 , 5)
