question 4 of 20
a ______ has two - fold rotational symmetry.
a. line
b. circle
c. square
d. equilateral triangle

Explanation:

A line has infinite - fold rotational symmetry. A circle has infinite - fold rotational symmetry. A square has four - fold rotational symmetry. An equilateral triangle has three - fold rotational symmetry. None of the options have two - fold rotational symmetry. But if we consider the closest concept, a rectangle (not in options) has two - fold rotational symmetry.

Answer:

None of the above options are correct.
