Answer:

See explanation

Step-by-step explanation:

A triangle PQR has its vertices at points P(1,-1), Q(3,-2) and R(3,-4).

A counterclockwise rotation by angle of 90° about the origin has the rule

[tex](x,y)\rightarrow (-y,x)[/tex]

Hence,

  • [tex]P(1,-1)\rightarrow P'(1,1);[/tex]
  • [tex]Q(3,-2)\rightarrow Q'(2,3);[/tex]
  • [tex]R(3,-4)\rightarrow R'(4,3).[/tex]

The image triangle is shown in attached diagram.
