Rotate PQR 270° counterclockwise
around the origin.

Rotating the triangle PQR to create an image of the triangle involves moving the triangle PQR in a circular direction
The coordinates of the triangle are given as:
P = (-10,15)
Q = (-20,5)
R = (-10,5)
The rule of rotation 270° counterclockwise around the origin is
[tex](x,y) \to (y,-x)\\[/tex]
So, we have:
P' = (15,10)
Q' = (5,20)
R' = (5,10)
Next, we plot the image of the triangle
See attachment for the image of triangle P'Q'R'
