Question

The angle obtained when a straight angle is bisected is.

• A. ${80}^{\circ }$
• B. ${90}^{\circ }$
• C. ${180}^{\circ }$

Answer 1

The correct option is B ${90}^{\circ }$

Straight angle is ${180}^{\circ }$ in measure.

The bisector of an angle divides the angle into two equal halves.

Therefore, the angle obtained$=\frac{180}{2}={90}^{\circ }$
