Algebraic Manipulation - Lesson 5 - Geometric Proof of Basic Algebraic Identities

There are 3 very important identities you will learn in lower secondary:

(a+b)^2
(a-b)^2
(a+b)(a-b)

Today I talk about the geometric proofs for these 3 identities. I think it's pretty interesting (although you don't really need to know the proof) and it helps foster a better understanding of the identities, so do take a look :)

Topic covered in O, N(A) and N(T) level.
