Triangle in Mathematics (Maths) Class 6
Triangle is a fundamental shape in geometry that is defined by three straight lines joining three non-collinear points. In Class 6 mathematics, students learn about the properties and characteristics of triangles. Here are some key points to understand about triangles:

Types of Triangles
- There are three main types of triangles based on their sides: equilateral, isosceles, and scalene.
- An equilateral triangle has all three sides of equal length, an isosceles triangle has two sides of equal length, and a scalene triangle has all three sides of different lengths.

Properties of Triangles
- The sum of interior angles in a triangle is always 180 degrees.
- The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
- The longest side of a triangle is opposite the largest angle, and vice versa.

Triangle Formulas
- The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.
- The perimeter of a triangle is the sum of the lengths of its three sides.

Special Triangles
- Right-angled triangles have one angle measuring 90 degrees.
- Pythagorean theorem can be applied to right-angled triangles to find the length of the third side.
Understanding the properties and formulas related to triangles is essential in solving geometry problems and real-life applications. Regular practice and application of these concepts can help students develop a strong foundation in mathematics.
