Web15 mei 2014 · Since $\angle AOC=120^{\circ}$ you have that rotation by $120^{\circ}$ will send one vertex to the next one namely $\sigma(1)=2,\sigma(2)=3,\sigma(3)=1$ Since the result is exactly the same triangle by rearranging the vertices it is a symmetry of the equilateral triangle (it would be helpful to read a formal definition of symmetry). Web25 jan. 2024 · The rotational symmetry of a shape describes how an object’s shape remains the same when rotated on its own axis. When turned \ ( {180^ {\rm {o}}}\) or with …
