Introduction to Triangles
A triangle is a simple closed figure formed by joining three non-collinear points. It has three sides, three angles, and three vertices. In RD Sharma Class 6 Chapter 12, students are introduced to the basics of triangles, including how they are formed and how they differ from other shapes.
Triangles are everywhere around us — from road signs to buildings — making this chapter both practical and interesting.
Key Concepts Covered in Chapter 12 Triangles
1. What is a Triangle?
A triangle is defined as a polygon with three sides. The three sides are connected end to end, forming a closed shape. The points where the sides meet are called vertices, and the lines are called edges.
2. Parts of a Triangle
Each triangle has:
3 sides
3 angles
3 vertices
Understanding these basic parts is crucial for solving all exercises in RD Sharma Class 6 Maths Solutions Chapter 12.
3. Types of Triangles Based on Sides
RD Sharma introduces different types of triangles based on their side lengths:
Equilateral Triangle: All three sides are equal.
Isosceles Triangle: Two sides are equal.
Scalene Triangle: All sides are different.
These classifications help students identify and solve problems more easily.
4. Types of Triangles Based on Angles
Triangles are also classified based on angles:
Acute Triangle: All angles are less than 90°.
Right Triangle: One angle is exactly 90°.
Obtuse Triangle: One angle is greater than 90°.
These concepts are essential for understanding geometry at higher levels.
Properties of Triangles
One of the most important concepts covered in RD Sharma Class 6 Chapter 12 is the properties of triangles:
The sum of the angles of a triangle is always 180 degrees.
A triangle cannot have more than one right angle or obtuse angle.
The length of any one side of a triangle is always less than the sum of the other two sides.
These properties are frequently used in solving exercise questions.
