Answer 1

Given -

Equilateral Triangle

To Find -

The number of rotations that will carry this equilateral triangle onto itself =?

Step-by-Step Explanation -

We know that in an equilateral triangle each question is of 60°

So,

Since it is a three-sided symmetry So, a rotation of 120° will carry this equilateral triangle onto itself.

Final Answer:

C. 120° counterclockwise rotation about its center P
