When a transversal intersects two lines then the angles formed at two distinct points on the same side of transversal such that one is exterior and other is interior are called _____ angles.
Fill in the blanks in each of the following to make the statement true: (i) If two parallel lines are intersected by a transversal then each pair of corresponding angles are ___ (ii) If two parallel lines are intersected by a transversal, then interior angles on the same side of the transversal are ___ (iii) Two lines perpendicular to the same line are ___ to each other. (iv) Two lines parallel to the same line are to ___ each other.
(v) If a transversal intersects a pair of lines in such a way that a pair of alternate angles are equal, then the lines are ___ (vi) If a transversal intersects a pair of lines in such a way that the sum of interior angles on the same side of transversal is 1800, then the lines are ___
The interior angles formed on same side of transversal when a transversal intersects two lines are called
If a transversal intersects a pair of lines in such a way that the sum of interior angles on the same side of transversal is 180∘, then the lines are__.
