Important Questions for Class 10 Maths Chapter 6 Triangles - Learn CBSE Now, solving this we get, ? Volume of frustum of the cone = (?)?h (r 12 +r 22 +r 1 r 2) Chapter 13, Surface Areas and Volumes, of class 10 Maths, is one of the most important chapters. The weightage of this chapter in the final exam is around 12 to 13 marks. ? = 90 / 10 ? = 9o (x) The height of a right circular cone is 12 cm and its volume is ??cm3. Find the lateral height of the cone. Solution: Since volume of cone = [1 / 3] ?r?h h = 12cm Volume = ?cm? [1 / 3] x ? x r? x 12 = ? 4? r? = ? r2 = / 4 r2 = 25 r = 5cm Slant height, l? = 5? + 12? l? = l . CBSE Class 10 Maths Solutions. SECTION B 7.

Chapter 14 - Statistics. Chapter 15 - Probability. Students were already introduced to the concept of Triangles in Class 9 wherein they studied properties such as congruence of Triangles. The introduction part of the chapter basically acts as a window for the students so that they are able to get an insight as to what would they be learning new under the topic of Triangles.

In this section of the Class 10 Maths Chapter 6, students are introduced to the concept of similar figures. Students are taught the basis of similarity in figures such as squares or equilateral triangles with the same lengths of Byjus Maths Class 9 Triangles Ltd the sides, circles with the same radii. As the students progress through this topic, they get to understand that similar figures can have the same shape but not necessarily the exact size. The questions from this topic mostly ask students to prove similarity between figures by applying the theorems.

Once the students are made familiar with Byjus Class 6 Maths Sample Paper Vol the concept of similarity, they are then introduced to the criteria under which two or more triangles are deemed similar. A thorough understanding of this topic will allow students to form the base for solving complex problems in higher mathematics. This section outlines and explains the criteria for the similarity of triangles.

The basic criteria for two triangles to be called similar include: if their corresponding angles are equal and if the corresponding sides of the triangles are in the same ratio or proportion. Students will be able to visualise the theorems as they are illustrated with the help of proper examples. Students can understand the formula and learn the process for finding the surface area of similar triangles in this section. Students have already learnt the theorem and its proof in Class 9.

In this section, students will learn how to prove this theorem by employing the concept of similarity of triangles. The summary comprises all the topics that you have studied in the chapter.

Going through the summary will allow you to recollect all that you have learnt in the chapter including the important concepts, theorems, etc. Book a Free Class.
