Question

How many times will an equilateral triangle look the same if rotated through a full rotation?

• A. None of the above
• B. 2
• C. 4
• D. 3

Answer 1

The correct option is D 3

• If we rotate the equilateral triangle by an angle 120 degree, it will look the same.
• After each 120 degree rotation, the equilateral triangle will look the same.
• Since one full rotation is 360 degrees, an equilateral triangle will look the same 3 times.
