Question

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

Answer 1

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

These are correct answers hope this helps. :)

Explanation:

Answer 2

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

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)
