§6.3 Applying the theorem

To calculate lengths we need

2 basic things:

a. a SKETCH and  

b. a SCHEME

So, in §6.3 ....

You are not given the right-angled triangles any more,

but you can easily:

+  make your own sketch of a right-angled triangle and

+  make the corresponding scheme, and finally

+  calculate the missing length !

Let's do exercise 16a together now!

Open your Notebook and make a 

+  SKETCH and a       

+  SCHEME, followed by calculating the distance.

Homework time.

Do: §6.3 ex 15,16, 17 and 19.

6.3 part 2

Exercise 18

A few tips for a few exercises!

What could the Sketch for 20 look like?

Like this:

Now 22, with a few difficult words:

1. What is a 'cylindrical barrel'?

2. What is the 'diameter' of a circle?

answer 1. Here are 2 cylindrical barrels:

answer 2: the diameter of a circle:

When doing 22...

Think back of this information,

making a good 

+  SKETCH and 

+  SCHEME, to

+  calculate the answer!

Questions?

Homework time again.

Good luck rounding off §6.3!
