Question

An angle bisector of a right angle divides the angle into ___________ angle(s).

• A. One ${45}^{\circ }$
• B. Two ${45}^{\circ }$
• C. One ${40}^{\circ }$
• D. One ${180}^{\circ }$

Answer 1

The correct option is B Two ${45}^{\circ }$

Right angle = ${90}^{\circ }$
An angle bisector divides an angle into two equal halves.
${90}^{\circ }÷2$ = ${45}^{\circ }$
$\therefore$ The angle bisector of a right angle divides it into two ${45}^{\circ }$ angles.
