Parallel Lines and Transversals
Transversals, interior and exterior angles made by them with a pair of parallel lines. Results on corresponding angles and alternate interior angles.
plz answer urgently dear experts lines and angles question :
If two lines are parallel then prove that any pair of bisictors of thier alternate interior angle is also parallel.
kindly give solution to the question in the image.
the diagram for the 8th question.
FIND X AN D Y
- If a transversal intersects two parallel lines, then prove that each pair of consecutive interior angles are supplementary.
- Show that in the given figure, AB || EF.
- If two lines are intersected by a transversal in such a way that the bisector of a pair of angles are parallel, show that the two lines are parallel.
