§6.1 Pythagoras' theorem

Before learning his so called famous theorem,

who was Pythagoras?

Pythagoras

1. is made up, never lived
2. invented the important number 'pi', for circles
3. founded a secret school and was a vegetarian
4. was a Greek philosopher from the 6th century BC

In the next slide you see...

+ what he could have looked like

+ even if he does not have the looks of a popstar

+ he still lookes quite fresh in our 21st century's eyes!

(except for the beard, perhaps...)

Some new words:

shorter sides  and  hypotenuse!

Homework time. 

Make a good start yourself. Later this is to be continued!

Pythagoras' theorem.

Next slide shows you shortly what it is all about!

Let's do exercise 4 together now.

Make all steps in your Notebook!

a.   Area smallest square = .............................

       Area greatest square = .........................

b.   Area square on hypothenuse = ..................................

c.   c = ........ 

In the next slide you see ......

a very handy scheme, to calculate the unknown side!

Copy this scheme and fill it in, with me!

Use this scheme....

doing exercises 5, 6 and many more in this chapter!

Homework time.

Now that you know Pythagoras a bit more,

+      make a good use of his Theorem

+      applying this in the Scheme we made in exercise 4

+      good luck!
