Question

A straight angle is geometrically equivalent to which fraction of a full circle rotation?

Options

• `1/4` turn

• `1/3` turn

• `1/2` turn

• `3/4` turn

Answer 1

`1/2` turn

Explanation:

A full circle measures 360°.

A straight angle measures 180°.

So, a straight angle is half of a full circular rotation, that is, a `1/2`  turn.
