In this Lecture 2 of our Geometry series, Shailesh Sir explains the core foundation of the "Similarity" chapter (specially for practice set 1.1). If you want to solve Practice Set 1.1 without any confusion, this video covers everything basic that you need.

What you will learn in this lecture:
✅ The basic formula: 1/2 . base . Height
✅ Case 1: Ratio of areas when nothing is common (Base and Height are different).
✅ Case 2: Ratio of areas with a Common Base.
✅ Case 3: Ratio of areas with a Common Height.
✅ Case 4: Ratio of areas when both Base and Height are Equal (Triangles between parallel lines).

Shailesh Sir uses simple diagrams and 3-4 practical examples for each case to ensure you can identify the base and height correctly every time. Master these 4 cases and you will never make a mistake in Practice Set 1.1!
