Question

What is the order of symmetry for the regular triangle?

• A. 0.0
• B. 2
• C. 4
• D. 3

Answer 1

The correct option is D 3

In a complete turn of ${360}^{\circ }$, the number of times an object looks exactly the same is called the order of symmetry.

If you rotate the triangle about the centroid for ${120}^{\circ },{240}^{\circ },{360}^{\circ }$ you will get the same triangle. So the order is 3.
