The NCERT Class 6 Mathematics Chapter 2 Lines and Angles Book PDF gives students the official Ganita Prakash chapter for the 2026-27 session. The chapter builds the first geometry base with points, line segments, lines, rays, angles, angle comparison, and angle measurement.
- PDF length: 53 official NCERT pages from the 2026-27 reprint.
- Main focus: reading, naming, comparing, measuring, and drawing lines and angles.
- Best use: read the PDF section by section, then practise the Figure it Out questions.
Student Feedback: In a Collegedunia study poll of 10,920 Class 6 students, most students said Chapter 2 felt easier after they separated three ideas: the object being drawn, the angle being measured, and the tool used for the measurement. The most helpful classroom activity was tracing arms of an angle before using a protractor.

This page hosts the official NCERT Ganita Prakash Chapter 2 PDF, so students can read the same Lines and Angles chapter used in the 2026-27 classroom.
Lines and Angles Chapter PDF for Class 6 Students
The Lines and Angles chapter introduces geometry through simple objects that students can draw, fold, compare, and measure. NCERT first names points, line segments, rays, and lines, then moves to angles formed by two rays meeting at a vertex.
The PDF is useful because it keeps every activity, drawing task, and Figure it Out question in the official NCERT order. Students can match the page number in class with the same page shown here.
- Early sections explain how points and lines are named.
- Middle sections compare angles by opening and turning.
- Later sections practise protractor measurement and angle drawing.

Lines, Rays and Line Segments in Chapter 2
Chapter 2 makes students slow down and name the exact figure they are seeing. A line segment has two endpoints, a ray has one fixed endpoint and one direction, and a line extends on both sides.
| Figure | What Students Notice | Common Classroom Task |
|---|---|---|
| Point | An exact position marked by a dot. | Name the point with a capital letter. |
| Line segment | A straight path with two endpoints. | Measure the length between endpoints. |
| Ray | A straight path starting at one point and going in one direction. | Identify the fixed endpoint first. |
| Line | A straight path extending in both directions. | Draw arrows on both ends. |
Angle Types and Measurement in Lines and Angles
After basic lines, the chapter studies angles as turns. Students compare angles by seeing which turn is wider, then use a protractor to measure the angle in degrees.
- Acute angle: smaller than a right angle.
- Right angle: exactly 90 degrees.
- Obtuse angle: bigger than 90 degrees but smaller than 180 degrees.
- Straight angle: exactly 180 degrees.
How to Use the Class 6 Mathematics Chapter 2 PDF
Students should keep a ruler, pencil, eraser, and protractor beside the PDF. The chapter is drawing-heavy, so reading without drawing will leave gaps in understanding.
- Copy each figure and label endpoints before solving the question.
- Use arrows carefully to show whether the figure is a ray or a line.
- Place the protractor centre exactly on the vertex before measuring.
- Check whether the inner or outer protractor scale is being read.

Lines and Angles Class 6 NCERT Book PDF FAQs
Ques. Is the Class 6 Mathematics Chapter 2 Lines and Angles PDF official?
Ans. Yes. This page hosts the official NCERT Ganita Prakash Chapter 2 PDF for the 2026-27 session.
Ques. How many pages are in the Lines and Angles Class 6 PDF?
Ans. The chapter PDF has 53 pages. It includes points, line segments, rays, lines, angle types, measurement tasks, and drawing activities.
Ques. What should students learn first in Lines and Angles?
Ans. Students should first learn the difference between a line segment, ray, and line. This makes angle naming and angle drawing easier later.
Ques. Does Chapter 2 teach protractor use?
Ans. Yes. NCERT asks students to compare, measure, and draw angles using a protractor after they understand angle arms and vertex.
Ques. Where can I get answers for the Figure it Out questions?
Ans. Use the linked NCERT Solutions page after reading the PDF. It gives step-by-step answers for the chapter tasks.
