C-10-Q139mediumsingle_mcq

The relation $\angle DAC = \angle ACB$ in the above figure holds because the two horizontal lines are—

aperpendicular
bintersecting
cparallel and $AC$ is a transversal
dcoincident

ব্যাখ্যা

The two horizontal lines are parallel and $AC$ acts as a transversal, so $\angle DAC$ and $\angle ACB$ are alternate interior angles, which are always equal.
