If the lines are intersected by a transversal and the co-interior angles are supplementary, then lines are .
If two parallel lines are intersected by a transversal, then alternate interior angles are equal.
If two parallel lines are intersected by a transversal then, pair of alternate interior angles are:
If two parallel lines are intersected by a transversal, then interior angles on the same side of the transversal are
Which of the following statements are true (I) and which are false (F)? Give reasons. (i) If two lines are intersected by a transversal, then corresponding angles are equal. (ii) If two parallel lines are intersected by a transversal, then alternate interior angles are equal. (iii) Two lines perpendicular to the same line are perpendicular to each other. (iv) Two lines parallel to the same line are parallel to each other. (v) If two parallel lines are intersected by a transversal, then the interior angles on the same side of the transversal are equal.
