Identify the transformation that maps the regular pentagon with a center (0, -2) onto itself.
a) reflect across the x-axis
b) rotate 90° about the point (0, -2)
c) rotate 144° about the point (0, -2)
d) rotate 180° about the origin (0, 0)

The answer is: C)Rotate 144° about the point (0, -2). I just took the test I promise this is correct.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
