§4.3 Right, acute, obtuse and straight

First we look back shortly at §4.2 Distances.

Finally the making of a circle:

a wonderful example of using 'distances'!

We look back at a more difficult exercise from §4.2 !

- open your Textbook on p.130, exercise 16 

- the Solution of 16 will be discussed on the C-Touch now

- COMPARE your answers to the books' ! 

We will study the questions and answers now, going back and forth between this slide and the next ones.

finally...

Look back at your own work:

- did you do 16 a, b, c and d well? Congrats!

- or did you make a few mistakes? Learn from your mistakes!

- didn't you do 16 at all?  What a pity. Only by trying hard yourself you

   learn a lot from discussing it. Not by leaning back.

Only now: 

§4.3 Right, acute, obtuse and straight angles !

What better way to Introduce all these new words and their meaning than watching an Englishman explaining it!?

(Only the first 3.14 minutes are important for us, now.)

The next 2 slides ...

summarise all the previous information!

Homework time
