Triangle ABC is rotated to form ​ △A'B'C' ​.The coordinates of point A are (1, 1) , the coordinates of point B are (3, 1) , and the coordinates of point C are (1, 4) .Which counter clockwise rotation around the origin results in the transformation of ​ △ABC ​​ to ​ △A'B'C' ​?

Answer:

Step-by-step explanation:

As we know the coordinate of point A = (1,1) , B = (3,1) and C = (1,4).

Rotate triangle ABC[tex]90^{0}[/tex] around the origin;

The rule for this transformation is:  (x,y) => (-y ,x)

  • A(1,1) => A' (-1,1) ,
  • B(3,1) => B'(-1 , 3) and
  • C(1,4)  => C' (-4,1)
