FAQs on Flashcard: Parallel Angles & Lines Video Lecture - Mathematics (Maths) Class 9

1. What are parallel angles?
Ans. Parallel angles are pairs of angles that are formed when two lines are intersected by a transversal and lie on the same side of the transversal.
2. How can you identify parallel lines?
Ans. Parallel lines can be identified by observing that they have the same slope and will never intersect, no matter how far they are extended.
3. What is the relationship between alternate interior angles and parallel lines?
Ans. Alternate interior angles are congruent when two parallel lines are intersected by a transversal, meaning they have the same measure.
4. How are corresponding angles related to parallel lines?
Ans. Corresponding angles are congruent when two parallel lines are intersected by a transversal, meaning they have the same measure.
5. Can vertical angles be parallel?
Ans. Vertical angles are not parallel since they are opposite angles formed by the intersection of two lines and do not have any relationship with parallel lines.
