NCERT Solutions Class 10 Maths Chapter 6 - Triangles

In class 10 maths triangles, you will get to know about the similarity of triangles and apply this knowledge in giving a simple proof of Pythagoras Theorem learnt earlier. Can you guess how heights of mountains (say Mount Everest) or distances of some long distant objects (say moon) have been found out? Do you think these have been measured directly with the help of a measuring tape? In fact, all these heights and distances have been found out using the idea of indirect measurements, which is based on the principle of similarity of figures.

The ncert solutions for class 10 maths chapter 6 provide detailed step-by-step answers to all exercises, helping students enhance their problem-solving skills and deepen their understanding of the subject. Class 10 maths chapter 6 solutions are valuable for exam preparation, ensuring that students are well-equipped to tackle questions related to triangles in their exams.
