📘 Chapter 5: Lines and Angles (NCERT Class 7 Maths)

🔹 Introduction

The chapter begins with a recall of basic geometry terms—points, lines, line segments, and rays. Students are introduced to angles, their types, and the special pairs of angles like complementary, supplementary, adjacent, linear pair, and vertically opposite angles. This lays the groundwork for solving angle-based problems and understanding angle properties when lines intersect or when a transversal cuts parallel lines.

📝 Exercise 5.1

This exercise focuses on the different pairs of angles such as complementary and supplementary angles. Students practice identifying whether given angle pairs add up to 90° or 180°.

👉 Concepts Covered:

Complementary Angles

Supplementary Angles



---

📝 Exercise 5.2

Here, students learn about adjacent angles, linear pairs, and vertically opposite angles formed by intersecting lines. They solve problems that use these properties to find unknown angles.

👉 Concepts Covered:

Adjacent Angles

Linear Pair of Angles

Vertically Opposite Angles



---

📝 Exercise 5.3

This exercise introduces the concept of a transversal cutting parallel lines. Students explore different angles formed, such as alternate interior angles, corresponding angles, and co-interior angles, along with their properties.

👉 Concepts Covered:

Transversal of Parallel Lines

Corresponding Angles

Alternate Interior Angles

Co-Interior Angles



---

📝 Exercise 5.4

The last exercise deals with practical applications of angle properties. Students use angle relationships in real-life and problem-solving contexts to calculate unknown angles in figures.

👉 Concepts Covered:

Applying Angle Properties

Finding Unknown Angles

Problem-Solving with Transversals and Parallel Lines
