07_Triangles &its  properties

Chapter Overview:

Dear Students

In this chapter, you will learn about the fundamental concept of triangles, including its definition, types, and properties. Students will understand the different types of triangles, such as equilateral, isosceles, scalene, right-angled, and oblique-angled triangles.

Key Concepts:

1. Definition of a Triangle: A polygon with three sides and three angles.

2. Types of Triangles: Equilateral, Isosceles, Scalene, Right-angled, and Oblique-angled triangles.

3. Properties of Triangles: Sum of angles, exterior angles, and side relationships.

4. Angle Sum Property: The sum of the interior angles of a triangle is always 180°.

Learning Objectives:

By the end of this chapter, you will be able to:

1. Define a triangle and identify its parts (vertices, sides, and angles).

2. Classify triangles based on their sides and angles.

3. Apply the angle sum property to find missing angles in a triangle.

4. Understand the relationship between the sides and angles of a triangle.

This chapter lays the foundation for more advanced geometry concepts in later classes and is essential for problem-solving in mathematics and real-life situations.
