Polygon ABCD has vertices A(-4,4), B(-1, 4), C(-3, 2), (-1, 1). Graph and label the vertices of
ABCD and its image A'B'C'D' after rotation it 90 degree counter clockwise. Choose the correct
ordered pairs of the image A'B'C'D'.

O A'(4.4). B'(4.1), C(2, 3), D(1,1)
A'(-4,-4), B'(-4,-1), C(-2,-3), D(-1,-1)

Answer 1

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

Explanation:

After counterclockwise 90 degree rotation X and Y coordinate swap and X coordinate changes its sign

Rotation of 90° (CounterClockwise) (x, y) ----->(-y, x)
