Question

Square PQRS is transformed as shown on the graph.

On a coordinate plane, 2 squares are shown. The first square has points P (negative 3, 5), Q (negative 1, 3), R (negative 3, 1), S (negative 5, 3). The second square has points P prime (negative 5, negative 3), Q prime (negative 3, negative 1), R prime (negative 1, negative 3), S prime (negative 3, negative 5).
Which rule describes the transformation?

R0, 90°
R0, 180°
R0, 270°
R0, 360°

Answer 1

R0, 90°

The square is rotated 90° counterclockwise about the origin. (Rule: (x,y) → (−y,x).)
