In all these videos on Lines and Angles from class 9th chapter 6 I have always focused on explaining the basics and then solving the questions. My way of solving question will always refer back to the basics explained previously so that students can make the connect between basics and application of them.
Let’s now start about the Lines and Angles from class 9th chapter 6:
Lines and Angles is actual start of the geometry as everything is drawn with the help of lines and if we know the properties of lines and he angles through them then we can solve almost all the problems. In this chapter we will deal with the very basic to the advance theorems of lines and angles.

Some basic geometrical Terminology
Axioms Vs Theorems
Line Segment Vs Ray Vs Line
More about Lines…
Collinear points
Intersecting Lines Vs Concurrent Lines
Two distinct lines can not have more than one common point
Parallel and Transversal Lines

Q & A
1) How many lines can be drawn to pass through a given point.
2) How many lines can be drawn to pass through two given point.
3) How many points can the two lines at the most intersect.
4) A ray AB is same as ray BA…..T/F
5) Two lines are parallel only when they have no point in common...............T/ F

Types of Angles:
Right, Acute, Obtuse, Straight, Reflex and Complete
Corresponding, Alternate, Consecutive Interior Angles
Bisector of an Angle, Vertically opposite Angles
Complementary Angles Vs Supplementary Angles
Questions from all the topics and exercises.

As per the syllabus, you will learn all the topics in my Lines and Angles Chapter Videos:
