Question

Bisecting a $120$ degree angle gives degree angle.

Answer 1

Bisector of a an angle, also called the internal angle bisector is the line or line segment that divides the angle into two equal parts.

So, $\frac{1}{2}\cdot {120}^{\circ }={60}^{\circ }$


$\therefore$ Bisecting a $60$ degree angle gives $30$ degree.
