  1. Does a equilateral triangle shape have rotational symmetry?

    I pretty sure the answer is yes

  2. 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.
