§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'!

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!

For VWO and H/V classes.

About the Challenge path:

+ Did you score high for the first tests?

   Then you are invited to try the Challenge path, 

   doing       C4 and C5 on p.135 ! (Of course everybody may try!)

+ However, C4 is a real challenge, especially C4b. This is about calculating

   precisely. The Solutionsbook does not make it much easier, I think. (All the 

   more as it contains a mistake.)

   So this is a REAL CHALLENGE!

Homework time

+  Make §4.3

+ Correct your work with the Solutionsbook

+ Take a few pics and 

+ Send them in on Google Classroom

+ Good luck!
