Does a equilateral triangle shape have rotational symmetry?
I pretty sure the answer is yes
Find the coordinates of the image of point R(3, -5) rotated 180 about the origin.
I think the answer is (-5,-3)

rotation through 180° changes both signs. So, (3,-5) -> (-3,5)
Did you actually plot your solution? You would see that it was nowhere near the rotated point.
an equilateral triangle has axial and rotational symmetry.
