One chance for changing oneself must be given to everyone. And Hari was a thief whose heart changes after realising the importance of education for his future. Question 2 Do you think it a significant detail in the story that Anil is a struggling writer? Does this explain his behaviour in any way?

Answer Yes, it is a significant detail in the story that Anil is a struggling writer. Hari Singh observed that Anil lifestyle was simple and used to spend according to his pocket at all time , he is getting irregular incomes and statement about his sale of a book to a publisher indicates that he is a struggling writer.

Can you think and imagine the circumstances that can turn a fifteen-year-old boy into a thief? Answer Yes, once i was travelling with my family in a train. In my compartment , some young boys were sitting.

After some time i realised that my small bag was missing. I got worried because my purse and other valuable were in that bag. I did not lose my temper and told them the story that how a thief transformed himself into a good person.

Similarly Hari Singh was an uneducated person belonging to a poor family. It was his circumstances that compelled him to become a thief. Its the circumstances that can turn a fifteen-year-old boy into a thief. Sides of triangles are given below. Determine which of them are right triangles. In case of a right triangle, write the length of its hypotenuse.

CD Solution:. ABC is an isosceles triangle right angled at C. ABC is an equilateral triangle of side la. Find each of its altitudes. Prove that the sum of the squares of the sides of a rhombus is equal to the sum of the squares of its diagonals. A ladder 10 m long reaches a window 8 m above the ground. A guy wire attached to a vertical pole of height 18 m is 24 m long and has a stake attached to the other end.

How far from the base of the pole should the stake be driven so that the wire will be taut? An aeroplane leaves an airport and flies due north at a speed of km per hour. At the same time, another aeroplane leaves the same airport and flies due Ncert Solutions Of Class 10th Chapter 5 Note west at a speed of km per hour. Two poles of heights 6 m and 11m stand on a plane ground. If the distance between the feet of the poles is 12 m, find the distance between their tops.

In an equilateral triangle, prove that three times the square of one side is equal to four times the square of one of its altitudes. Prove that Solution:. Prove that the sum of the squares of the diagonals of parallelogram is equal to the sum of the squares of its sides. In the given figure, two chords Ab and CD of a circle intersect each other at the point P when produced outside the circle. Nazima is fly fishing in a stream. The trip of her fishing rod is 1.

Once the students are made familiar with 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. The list of exercise in the Maths Class 10 Chapter 6 has been provided below:.
