Line l and m are parallel to each other. A transversal intersects them at points A and B.
i) An arc of suitable measure is taken from B cutting ‘l’ at D and transversal at M (as shown in the figure).
ii) Now, with the same radius and A as centre an arc FG is drawn (as shown in the figure).
What is the relation between ∠FAG and ∠MBD?
alternate interior angles
Alternate interior angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.
In above figure, ∠FAG and ∠MBD are alternate interior angles.
