§6.2 Calculating a side
Do you remember our old, bearded friend from the past?
Slide 1 - Slide
Who is he?
Slide 2 - Mind map
§6.2 Calculating a side
Welcome back to: Pythagoras!
Next slide shows us another picture
of this great Maths chap, that coud've been anybody's neighbour. Or uncle, for that matter...
Slide 3 - Slide
Slide 4 - Slide
The theorem of Pythagoras
A
is about the sides of a right-angled triangle
B
is used to calculate an unknown side
C
is invented by Pete Agoras
D
is more than 2000 years old but still going strong
Slide 5 - Quiz
The theorem of Pythagoras...
asks for the use of a very handy scheme!
Slide 6 - Slide
Let's do exercise 8 together,
start doing 8 a), making a sketch!
Slide 7 - Slide
Here is the sketch:
Slide 8 - Slide
Now think hard about b:
Slide 9 - Slide
answer for b:
Slide 10 - Slide
Do c now:
First copy the scheme! Then:
Slide 11 - Slide
answer for c:
Slide 12 - Slide
Slide 13 - Slide
Time to do d:
Slide 14 - Slide
answer for d:
'exact' is not rounded off!
Slide 15 - Slide
Homework time.
Do §6.2 now,
+ start with 7, then 9, 10, etcetera
+ make the SCHEME with lengths for every exercise!!
+ remember to place the hypotenuse (=longest side) at the bottom
+ later on this LessonUp is continued
Slide 16 - Slide
A few fine points from this paragraph follow now!
Slide 17 - Slide
How to calculate length BD?!
Slide 18 - Slide
We want to calculate BD.
What to calculate first?
Slide 19 - Mind map
Solution: First calculate length CD in right-angled triangle ACD.
Then only calculate length BD in right-angled triangle BCD!
Slide 20 - Slide
One more new thing from §6.2!
Slide 21 - Slide
How (on earth) can you calculate DE or GH?
We do not even have a right-angled triangle!
Slide 22 - Slide
How to calculate these lengths?
Slide 23 - Mind map
Solution: we make a right-angled triangle ourself!!
With that we can make the SCHEME and calculate the unknown side.
In the next slide you see Pythagoras, going crazy about his Theorem once more...
Slide 24 - Slide
Slide 25 - Slide
Homework time again.
Finish as much as you can!
