Meaningful Equations: Some formulae (in advance)

Have you ever wonder how some of these formulae are derived or how to verify some of them?

1. The Pythagoras Theorem

There are 2 clips that's shared during the lesson relating to the Pythagoras' Theorem:

2. Area of Trapezium

Do you know, we can derive the formula for the area of a Trapezium using area of triangle and factorisation?

 

3. Surface area of a sphere
