In this video, we dive into Chapter 10: Practical Geometry, focusing on Exercise 10.2 from the Class 9 Mathematics Federal Board (National Book Foundation) syllabus. We will thoroughly explain the construction of altitudes in triangles and how to find their point of concurrency, also known as the orthocenter.

Topics Covered:

How to draw the altitudes of a triangle using a compass and ruler.

Understanding the concept of altitudes and their role in triangle geometry.

Step-by-step guide to locating the orthocenter, the point where all three altitudes intersect.

Practical examples and tips for accurate construction.


This video is perfect for Class 9 students preparing for board exams and anyone looking to strengthen their geometry skills!

Key Points:

Federal Board syllabus (National Book Foundation)
