In the figure below, lines AB and CD intersect each other at point O. If the angle $\angle AOD={110}^{\circ }$ then, $\angle AOC$ is

In the figure below, lines AB and CD intersect each other at point O. Angles ($\angle$ AOD, $\angle$ COB) and ($\angle$ AOC, $\angle$ BOD) are called ___.

In the figure below, lines AB and CD intersect each other at point O. The angle pairs ( $\angle AOD$ and $\angle COB$) and ( $\angle AOC$ and $\angle BOD$) are called ___.

In the figure below, lines AB and CD intersect each other at point O. If the angle $\angle AOD={80}^{\circ }$ then, $\angle BOC$ is

Let AB and CD be two lines intersecting each other at O. If the ratio of ∠COB and ∠AOC is 5:4, then the measure of ∠AOD will be
