§2.2 Pie chart

In dutch we talk about:   een cirkeldiagram.

The English have a much more tasty name for it.

They like pie and also pie chart.

But WHAT IS IT ?!

Let's watch one in the next slide!

For drawing a pie chart, 

you need to know how large every angle is.

Next slides show how to Calculate the Angles!

The Method that is

used here, is to be

found on p.49 too! 

In order to do §2.2 you need the right materials:

- a pair of compasses

- a ruler or geo triangle

- a pencil

So take them before you on your desk!
