Question

What are the coordinates of each point after quadrilateral ABCD is rotated 270° about the origin?​

Answer 1

Answer:

• A'(1, -1), B'(3, -2), C'(3, -4), D'(1, -5)

Step-by-step explanation:

The rule for a rotation by 270° about the origin is:

• (x, y) → (y, −x)

Coordinates of ABCD:

• A(1, 1), B(2, 3), C(4, 3), D(5, 1)

Coordinates of the image:

• A'(1, -1), B'(3, -2), C'(3, -4), D'(1, -5)

Answer 2

Answer:

A'(1,-1)  , B'(3,-2)  , C'(3,-4)  , D'(1,-5)

These are correct answers hope this helps. :)
