Question

write the order and angle of rotation symmetry of an equilateral triangle ​

Answer 1

Answer:

The images B and C are generated by rotating the original image A. When we look at the above images of equilateral triangle, it fits on to itself 3 times during a full rotation of 360 degrees. Hence, an equilateral triangle has rotational symmetry of order 3.

Answer 2

Answer:

In a complete turn (of 360°), the number of times an object looks exactly the same is called the order of rotational symmetry. The order of symmetry of a square, for example, is 4 while, for an equilateral triangle, it is 3.
