Master Chapter 2 Class 6 - Lines And Angles (Ganita Prakash) with comprehensive NCERT Solutions, Practice Questions, MCQs, Sample Papers, Case Based Questions, and Video lessons.
Start Learning NowHave you ever wondered how all the shapes we see are drawn? It all begins with the simple ideas in this chapter from your Class 6 Ganita Prakash textbook. This is where we start our journey into the world of geometry.
We will learn how a single dot, or point, is the start of everything. From there, we'll explore how points form lines, and how those lines come together to create angles—the building blocks for triangles, squares, and every other shape.
Here is a look at the key topics we will cover:
The Building Blocks: We will learn the exact definitions of:
Point: A tiny dot that shows a precise location.
Line Segment: The shortest path between two points, which has two end points.
Line: A line segment that extends forever in both directions.
Ray: A portion of a line that starts at one point and goes on endlessly in one direction.
Understanding Angles: We’ll discover what an angle is and how it is formed by two rays that share a common starting point, called the vertex.
Types of Angles: You will learn to identify important angles by their size and name:
Acute Angle (less than a right angle)
Right Angle (formed by folding a straight angle in half)
Obtuse Angle (greater than a right angle but less than a straight angle)
Straight Angle (an angle that forms a straight line)
Reflex Angle (an angle greater than a straight angle)
Measuring Angles: We will learn about degrees (like 90°) and how to use a protractor to measure any angle accurately.
These new terms are the foundation for all of geometry. To help you build a strong base, Teachoo has prepared a clear, step-by-step guide for every topic in this chapter.
