How many rotational symmetry of a triangle
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). WebI.e. if two triangles are rotated 90 degrees from each other but have 2 sides and the corresponding included angles formed by those sides of equal measure, then the 2 …

WebThe order of rotational symmetry of a regular polygon is the same as the number of sides of the polygon. You can also deduce the order of rotational symmetry by knowing the smallest angle you can rotate the shape through to look the same. 180° = order 2, 120° = order 3, 90° = order 4. The product of the angle and the order would be 360°.
