plz give me correct answer only otherwise I will report your answer

1) equilateral triangle
2) circle
3) regular hexagon
Answers
Answer:
1) Equilateral Triangle
The order of rotation would be 3 and the angle of rotation would be 120 degrees
Order of rotation of a figure is the number of the exact replicas of the figure we would get if we rotate the figure over a course of 360 degrees.
Angle of rotation is the minimum angle we must rotate a figure to get an exact replica of the figure.
An equilateral triangle has an order of rotation of 3 and an angle of rotation as 120 degrees
2) Circle
Infinite
3) Regular Hexagon
The order of symmetry is the number of times the figure coincides with itself as its rotates through 360° . A regular hexagon has rotational symmetry. The angle of rotation is 60° and the order of the rotational symmetry is 6.
