17.2 Vorm ander groepe van drie elk. Volg dieselfde instruksies as in 17.1, maar bou nou ’n reghoek. As jy op die hoekpunt druk, sal dit in ’n parallelogram verander.

• Vergelyk nou die reghoek met die parallelogram en voltooi die tabel:

18. Wat noem ons hierdie meetkundige figure?

a)

__________________________________________

b)

__________________________________________

19. Deel in groepe van vier. Jul opvoeder sal julle sê wie a,b,c en d moet doen.

19.1 Hou ’n bespreking oor die ooreenkomste en verskille tussen:

a) ’n ruit en ’n vlieër

b) ’n trapesium en ’n parallelogram

c) ’n reghoek en ’n trapesium

d) ’n vlieër en ’n trapesium

19.2 Maak ’n plakkaat om bogenoemde te verduidelik en gee terugvoering aan die klas.

20. Het jy geweet?

In Wiskunde sê ons ’n figuur is stewig as hy sy oorspronklike vorm behou, indien druk op een van die hoekpunte toegepas word, bv.

Nie stewig nie

Stewig

20.1 Verdeel nou in pare. Gebruik koeldrankstrooitjies en bou enige stewige konstruksie. Kyk dan of julle die hoogste konstruksie in die klas kan bou!

20.2 LET OP!

’n Driehoek is die enigste veelhoek wat rigied / stewig is. Dit verander nie van vorm as jy op enige punt van die raam druk nie.Waar, dink jy, word driehoeke gereeld deur ingenieurs en bouers gebruik om stabiliteit te verseker?

21. Tyd vir selfassessering

 Merk die toepaslike kolom. Onseker Seker Ek kan verduidelik wat die volgende is: ’n veelhoek ’n konvekse veelhoek ’n konkawe veelhoek ’n reëlmatige veelhoek ’n onreëlmatige veelhoek Ek ken die formule om die hoeke van ’n reëlmatige veelhoek te bereken Ek kan ooreenkomste tussen die verskillende meetkundige vorms uitwys Ek kan die verskille tussen die verskillende meetkundige vorms uitwys Ek kan ’n stewige konstruksie m.b.v. koeldrankstrooitjies bou

## Assessering

Leeruitkomste 3: Die leerder is in staat om eienskappe van en verwantskappe tussen twee-dimensionele vorms en drie-dimensionele voorwerpe in ‘n verskeidenheid oriëntasies en posisies te beskryf en voor te stel.

Assesseringstandaard 3.1: Dit is duidelik wanneer die leerder meetkundige figure en drie-dimensionele voorwerpe in natuurlike en kulturele vorms en ‘n meetkundige agtergrond herken, visualiseer en benoem, insluitend dié wat vroeër behandel is;

Leeruitkomste 2: Die leerder is in staat om patrone en verwantskappe te herken, te beskryf en voor te stel en probleme op te los deur algebraïese taal en vaardighede te gebruik.

Assesseringstandaard 2.3: Dit is duidelik wanneer die leerder voorstellings maak van en verwantskappe tussen veranderlikes gebruik sodat inset- en/of uitsetwaardes op ‘n verskeidenheid maniere bepaal kan word.

are nano particles real
yeah
Joseph
Hello, if I study Physics teacher in bachelor, can I study Nanotechnology in master?
no can't
Lohitha
where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts
Bhagvanji
hey
Giriraj
Preparation and Applications of Nanomaterial for Drug Delivery
revolt
da
Application of nanotechnology in medicine
has a lot of application modern world
Kamaluddeen
yes
narayan
what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
how did you get the value of 2000N.What calculations are needed to arrive at it
