The rule for a rotation by 270 ° about the origin is (x,y) ⇒ (y,-x)
Rotating the triangle PQR to create an image of the triangle involves moving the triangle PQR in a circular direction.
The coordinates of the given triangle are:
- P = (-10,15)
- Q = (-20,5)
- R = (-10,5)
Using the rule, the coordinates now are:
- P' = (15,10)
- Q' = (5,20)
- R '= (5,10)
In the attatchment, the answer is in pictoral form.
