Question 3 • CMS 2026-2027 NC Math 2 CREDIT RECOVERY

One vertex of a polygon is located at (3,−2). After a rotation, the vertex is located at (2, 3). Which transformations could have taken place? Choose two correct answers.

Answer
A
cap r sub 0 comma 180 degrees
B
cap r sub 0 comma negative 90 degrees
C
cap r sub 0 comma negative 270 degrees
D
cap r sub 0 comma 270 degrees
E
cap r sub 0 comma 90 degrees

Explanation

A 90° counterclockwise rotation about the origin maps (x, y) to (−y, x). Applying it to (3, −2) gives (2, 3), so a 90° rotation works. A rotation of −270° is equivalent to 90°, so both −270° and 90° are correct.
