Jy het gesien hoe om meetkunde en die eienskappe van poligone te gebruik om die onbekende lengtes van sye en die groottes van hoeke van verskeie vierhoeke en poligone te vind. Ons gaan nou hierdie werk uitbrei om sommige van die eienskappe te bewys en probleme op te los. ʼn Vermoede is ʼn wiskundige se manier om te se: "Ek glo dit is waar, maar ek het geen bewys nie". Die volgende uitgewerkte voorbeelde sal help om dit duideliker te maak.
Gegee vierhoek ABCD, met
en
, bewys dat
en
.
Ons maak die volgende skets en trek die diagonale.
Gegee:
en
. Ons moet bewys
en
. In formele wiskundetaal sê ons dat ons gevra word om te bewys (RTP='requested to prove'):
en
.
Net so vind ons dat:
In parallelogram ABCD, is die halveerlyne van die hoeke (AW, BX, CY en DZ) gekonstrueer:
Dit word ook gegee dat
,
,
,
,
, en
.
Bewys dat MNOP parallelogram is.
Gegee:
,
,
,
,
, and
. Bewys MNOP is ʼn parallelogram.
MNOP is ʼn parallelogram (beide pare teenoorstaande
'e
, daarom is beide pare teenoorstaande sye ook parallel)
Dit is baie belangrik om daarop te let dat ʼn enkele teen-voorbeeld genoeg is om ʼn vermoede verkeerd te bewys. Selfs ʼn menigte ondersteunende voorbeelde is nog steeds geen bewys nie!
It depends on the type of infection. Bacterial, fungal, parasitic or viral?

The lymphatic system plays several crucial roles in the human body, functioning as a key component of the immune system and contributing to the maintenance of fluid balance. Its main functions include:
1. Immune Response: The lymphatic system produces and transports lymphocytes, which are a type of
asegid
to transport fluids fats proteins and lymphocytes to the blood stream as lymph
Anatomy is the study of the structure of the body, while physiology is the study of the function of the body. Anatomy looks at the body's organs and systems, while physiology looks at how those organs and systems work together to keep the body functioning.
Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more. Too much or too little of a certain enzyme can cause health problems

how does the stomach protect itself from the damaging effects of HCl
the normal temperature is 37°c or 98.6 °Fahrenheit is important for maintaining the homeostasis in the body
the body regular this temperature through the process called thermoregulation which involves brain skin muscle and other organ working together to maintain stable internal temperature
