Is an equilateral triangle a centrosymmetric figure?

no
Definition of centrosymmetric figure: in the same plane, if a figure is rotated 180 ° around an internal point, the rotated figure can completely coincide with the original figure, then the figure is called centrosymmetric figure. Regular triangle can't, so it's not
