Polygon ABCD is shown below. Which of the following transformations will map it into itself? Select all that apply. a. Reflection around line EF
b. Rotation of 120 degrees around the origin
c. Rotation of 90 degrees around the origin
d. Reflection around line segment DC.
e. Reflection around line segment BC

A and C I think. I'm not completely sure though.

idk this answer sorry cant on this one.

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
