## FAQs on RD Sharma Class 6 Maths Solutions Chapter 12 - Triangles

**1. How do you introduce a triangle?**

A triangle is defined as a closed curve made up of three line segments. The sides of the triangle are the line segments that make up the triangle. The vertices of the triangle are the points where the sides of the triangle intersect. The angles of the triangle are the angles formed at the vertices.

**2. How important are RD Sharma Solutions of Class 6 Maths Chapter 12 for students?**

Triangles are one of the first geometric forms to be studied. Triangles are extremely important since they can be decomposed from arbitrary polygons (with 4, 5, 6, or n sides). Understanding the fundamental properties of triangles allows for a more in-depth study of these larger polygons. Hence, studying triangles is basic for higher-level mathematics in geometry.

**3. Where can I find the RD Sharma Class 6 Triangles Solutions?**

Students can find the free PDF of RD Sharma Class 6 Triangles Solutions on the Vedantu platform. Also, Vedantu provides free PDF solutions to all classes and chapters of RD Sharma according to the NCERT curriculum for free.

**4. How to introduce a triangle to a class 6 student?**

A triangle is a 2d folded polygon that has three sides. A triangle has three line segments that intersect each other at a point called vertice. A triangle has three interior angles as well as three exterior angles. Each interior angle is 60 degrees and together all interior angles are 180 degrees. All exterior angles are 120 degrees and together all are 360 degrees. Teachers can use the latest tips given on Vedantu for introducing a triangle to a class 6 student.

**5. Where can students find the RD Sharma solutions of class 6 chapter 10 triangles?**

As per the NCERT curriculum, NCERT books are recommended. But they do not have all the solutions to the problems. So, RD Sharma is a good reference book to opt for. RD Sharma Solutions are available on Vedantu. Students can download pdf from Vedantu’s official site for free. They just have to register them on the website forum and can go through each and every solution. The RD Sharma Solutions for Class 6 Maths chapter 12 are prepared by expert teachers for quick and easy understanding of the students.

Chapter 12 Triangles is an important chapter for class 6. This chapter is a base level for the students to understand the plane figures, which includes three non-parallel line segments. Vedantu gives all the information that is necessary for a class 6 student to go through. The chapter - triangles focus on a particular shape with different sides, sizes, and angles. A Triangle has three line segments, folded together to make a triangle. The sides of the triangle are called line segments. Two line segments meet at a point, called Vertice. A triangle has three vertices, three sides, and a three-line segment. A triangle is called a three-sided polygon. RD Sharma is a valuable book for the students to read for more reference.

**Properties of a Triangle**

Every shape has its unique property, the triangle has the same. Major properties of the triangles are mentioned below-

A triangle has three sides and three vertices.

All the interior angles together are of 180 degrees

All the exterior angles together are 360 degrees.

The sum of consecutive exterior and interior angles is supplementary

The smallest interior angle and the smallest sides are opposite of each other.

**Angles of triangle**

A regular triangle has three interior angles of 60 degrees each, together with equal to 180 degrees. also by extending the line segments make an exterior angle of 120 degrees each. An exterior and interior angle together is 180 degrees each.

**Types of Triangle**

Triangles are of three types based on length of sides-

Scalene Triangle - In a triangle in which all the three sides are of different measure i.e. called a scalene triangle.

Isosceles Triangle - A triangle that has a minimum of two sides of equal measure is called an isosceles triangle.

Equilateral Triangle - A triangle with all sides of equal measures is called an equilateral triangle.

**Triangle is also of three types based on interior angles-**

**Acute angle triangl**e - A triangle with all angles less than 90 degrees is called an acute angle triangle.**Right angle triangle**- A triangle that has an angle equal to 90 degrees is called a right angle triangle.**Obtuse angle triangle**- A triangle with an angle equal to more than 90 degrees is called an obtuse angle triangle.

**Area and Perimeter of Triangle**

An area of a triangle is calculated as per the region occupied in a 2d space.

Area of Triangle = ½ x Base x Height

The parameters of a triangle are calculated as per the total length of the boundaries of the triangle.

Parameter of Triangle = Sum of all sides
