Question

In the construction of a right angle, what is the first basic angle that would be obtained? (in degrees)

• A. 180°
• B. ${270}^{\circ }$
• C. ${180}^{\circ }$
• D. ${45}^{\circ }$

The correct option is C

${180}^{\circ }$

We first draw a straight line and bisect it to get ${90}^{\circ }$. The angle that the straight line produces is ${180}^{\circ }$.
