Which regular polygon has a rotation of 240 degree to carry the polygon onto itself? Equilateral triangle

Octagon

Rectangle

Pentagon

With regard to the regular hexagon, the student describes the center of rotation as the point where the diagonals intersect. The student indicates that rotations of degree 60, 120, 180, 240, 300, and 360 clockwise and counterclockwise about this point will carry the hexagon onto itself.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
