yes the rotation symmetry of an equilateral triangle is 3
Three.

120
reflective (aka reflection)
That will depend on what type of triangle it is and if it is an equilateral triangle then it will have rotational symmetry to the order of 3
Rotational symmetry is based on points of rotation not lines
order of rotation of a semi circle is 1
It is to the order of 3
An equilateral triangle has rotational symmetry (order 3).
