Pythagoras theorem proof questions....?
One day he decided to find a proof of the Pythagoras theorem: a² + b² = c².
Garfield has the idea to draw a trapezium with 2 right angles of sides a, b & c, and a right isosceles triangle with 2 sides equal to c. Here is how he proceeded:
1. Calculate the area of the trapezium by 2 ways using a, b & c.
2. Write an equation using the 2 formulae you have just found.
3. Simplify the equation and conclude.
Please help...!?? Thanks everybody.
