Question

Write
order
of
rotation
and
angle
of


rotation
of
:


(i) Equilateral
triangle


(ii) Circle


(iii) Regular
hexagon​

Answer 1

Given : :(i) Equilateral triangle(ii) Circle(iii) Regular hexagon

To Find : order of rotation

(i) 3 , (ii) infinity , (iii ) 6

(i) 3 , (ii) infinity , (iii ) 5

(i) 2 , (ii) infinity , (iii ) 5

(i) 3 , (ii) 0 , (iii ) 6​

angle of rotation

Solution:

(i) Equilateral triangle

order of rotation = 3

angle of rotation  = 360 / 3  = 120°

(ii) Circle

order of rotation = Infinity

angle of rotation  = 360 / ∞  =  0°

(iii) Regular hexagon

order of rotation = 6

angle of rotation  = 360 / 6  =60°

order of rotation   (i) 3 , (ii) infinity , (iii ) 6   respectively for (i) Equilateral triangle(ii) Circle(iii) Regular hexagon

Angle of rotation    (i) 120° , (ii) 0° , (iii ) 60°   respectively for (i) Equilateral triangle(ii) Circle(iii) Regular hexagon
