Question

16. Quadrilateral ABCD with vertices A(4,0),

B(6,-2). C(8,-7), and D(
0-5):
270° counterclockwise about the origin.

Answer 1

A (4,0) becomes (0,4)

B (6,-2) becomes (2,6)

C (8,-7) becomes (7,8)

D (0,-5) becomes (5,0)

Explanation:

By moving a point 270 degrees counterclockwise around the origin, we have the following change;

(x,y) becomes (-y,x)

A (4,0) becomes (0,4)

B (6,-2) becomes (2,6)

C (8,-7) becomes (7,8)

D (0,-5) becomes (5,0)
