MCQ
Which one of the following is correct $?$
  • A
    If two lines are intersected by a transversal, the alternate angles are equal.
  • B
    If two lines are intersected by a transversal then sum of the interior angles on the same side of transversal is $180^\circ .$
  • C
    If two lines are intersected by a transversal then corresponding angles are equal.
  • All of these.

Answer

Correct option: D.
All of these.
If two parallel lines are cut by a transversal, the corresponding angles are equal.
If two parallel lines are cut by a transversal, the alternate interior angles are equal.
If two parallel lines are cut by a transversal, the interior angles on the same side of the transversal are supplementary.
Hence all options are correct.
