Question

What is the measure of $\angle$AOD + $\angle$AOH ?

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

Answer 1

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

On combining both the given angles, we get a straight angle $\angle$HOD.
​​
$\angle$AOD + $\angle$AOH = $\angle$HOD


As we know, the measure of a straight angle is always ${180}^{\circ }$.
Hence, $\angle$AOD + $\angle$AOH = ${180}^{\circ }$
