Question

By what angle does a soldier turn when he takes an "about turn"?

• A. ${90}^{\circ }$
• B. ${180}^{\circ }$
• C. ${360}^{\circ }$

Answer 1

The correct option is B ${180}^{\circ }$

When a soldier takes an "about turn" he turns by ${180}^{\circ }$, since he turns by a measure equal to two right angles.
