Question

A line has____ rotational symmetry. A. Four-fold B. Six-fold C. Two-fold D. Seven-fold

Answer 1

`\boxed{\mathrm{C}}`

Explanation:

A line has two-fold rotational symmetry.

The line rotated two times from a central point remains the same.

Or the line rotated 180 degrees from a central point remains the same.

Answer 2

Option C

Explanation:

A line has a 2-Fold rotational symmetry because if we rotate the line about 180, The resulting thing will be the same line.
