# Solve both the questions 1. (a) Can you now tell the order of the rotational symmtery for an equilateral triangle ( Fig 14.14) (b) How many position are there at which the triangle looks exactly the same when rotated about its center by 120 o ? 2. Which of the following shapes (Fig 14.15) have rotatinal symmetry about the marked point.

Dear student
Que 1 a) order of the rotational symmtery for an equilateral triangle is 1
b) We observe that at all 3 positions, the triangle looks exactly the same when rotated about its center by 120$°$

For remaining queries we request you to post them in separate threads to have rapid assistance from our experts.
