Question

In the given figure below points $A,O$, and $C$ lie on the same line. What is the sum of the measures of $\angle AOD$ and $\angle DOC$?

• A. ${90}^{\circ }$
• B. ${180}^{\circ }$
• C. ${270}^{\circ }$
• D. ${360}^{\circ }$

Answer 1

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

Since $AOC$ forms a straight line,
Sum of the measures of $\angle AOD$ and $\angle DOC={180}^o$
