Quadrilateral abcd is rotated 90 degrees clockwise about the origin. What are the coordinates of A'B'C'D?

Option B is correct.

The coordinate of A' is (-2 , -1)

Explanation:

The coordinates of ABCD are A = (-1,2) , B(1,1) , C =(1,-1) and D(-2,-2).

Rotation means moving the shape  around a fixed point clockwise or anticlockwise, and by a certain number of degrees.

Rule for 90° counterclockwise rotation about the origin:

or we can say that switch x and y in the coordinates and make y value opposite.

Then, the coordinate of A' :

Therefore, the coordinate of A' in the quadrilateral A'B'C'D' is, (-2 ,-1)

your answer is A
