# ICSE Class 9 Mathematics Revision Notes Chapter 13 – Pythagoras Theorem

The Pythagoras Theorem is a Mathematical theorem that states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. While this theorem is relatively simple, it can be used in many situations and has had a profound impact on Mathematics and Physics. Students can learn more about Pythagoras Theorem with the help of the ICSE Class 9 Mathematics Revision Notes Chapter 13.

The Pythagoras theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. For example, in a right triangle with side lengths of 3 and 4, the square of the length of the hypotenuse (the longest side) is 12. The sum of the squares of the lengths 3 and 4 (9) is greater than the square of the length of the hypotenuse (12), so there must be a third side to this triangle. This side is 5, and it is called the Pythagorean theorem. This is well explained in the ICSE Class 9 Mathematics Revision Notes Chapter 13.

Mathematics is a challenging subject, but that does not mean it is impossible. There are many challenges that students can face when practising Mathematics, but with the right strategy, they can overcome them. One of the most common challenges students face is understanding concepts challenging to comprehend. Either they succumb to rote learning or couldn’t care less, attitude follows since the syllabus is vast and it takes time to master the topic. If a student understands the concepts behind a problem, they are more likely to be able to solve it. Students also must accept the fact that   making mistakes is acceptable, it’s the first step to learning. In fact the more mistakes you make the better you learn! Mistakes are a part of learning, and if a student can learn from their mistakes, they will learn  better. They can easily handle similar problems without much difficulty.They are well prepared for future challenges. Multiple approaches can be learned with   ICSE Class 9 Mathematics Revision Notes Chapter 13.

Experts make Mathematics simple and scoring for each one of the students  by providing the  best study materials from a popular website known as Extramarks.
