At which angle will the hexagon rotate onto itself?

The correct answer is: 60°  

Step-by-step explanation:

Rotational symmetry is a type of symmetry, in which an object returns back to its original shape after rotation at an angle of 360°/n about a fixed point.

A hexagon is a regular polygon that has six edges and vertices. It has six internal angles, 120° each.

Since there are 6 equal edges, therefore, the hexagon will rotate onto itself after every rotation at an angle of: 360°/n = 360°/6 = 60°

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

english, cause i can’t you
