Question

Triangle QRS is transformed as shown on the graph. On a coordinate plane, 2 triangles are shown. The first triangle has points Q (2, negative 1), R (5, negative 2), S (4, 1). The second triangle has points Q prime (negative 1, negative 2), R prime (negative 2, negative 5), S prime (1, negative 4). Which rule describes the transformation? R0, 90° R0, 180° R0, 270° R0, 360°

Answer 1

270°

Explanation:

Q: (2,-1) --> (-1,-2)

R: (5,-2) --> (-2,-5)

S: (4,1) --> (1,-4)

In general

(x , y) --> (y, -x)

90° clockwise rotation

270° anti-clockwise rotation
