Question

Triangles def and d′e′f′ are shown on the coordinate plane below: triangle def and triangle d prime e prime f prime with ordered pairs at d negative 1, 6, at e 1, 3, at f 6, 3, at d prime 6, 1, at e prime 3, negative 1, at f prime 3, negative 6. what rotation was applied to triangle def to create triangle d′e′f′?

a. none of the above
b. 90°
c. counterclockwise 180°
d. 90° clockwise

Answer 1

Triangle d′e′f′ was obtained by rotating triangle def 90° clockwise about the origin.

Step-by-step explanation:

To determine what rotation was applied to triangle def to create triangle d′e′f′, we can compare the coordinates of the corresponding points. By observing the coordinates, we can see that triangle d′e′f′ is obtained by rotating triangle def 90° clockwise about the origin.
