Inhoud

Onthou jy nog wat die woord ewewydig beteken? Skryf gou ‘n definisie neer:

_____________________________________________________________________

_____________________________________________________________________

_____________________________________________________________________

Kom ons val weg met ‘n paar “kopkrappers”!

Kyk na die sketse hieronder en beantwoord dan die vrae:

Figure 1
Figure 1 (graphics1.png)

1. Is EF en GH ewewydig aan mekaar in:

A: __________________________________________________________________

B: __________________________________________________________________

2. Is C of K die verlenging van F?

Figure 2
Figure 2 (graphics2.png)

Onthou jy nog?

Table 1
graphics3.png is ‘n lyn: AB
graphics4.png is ‘n lynstuk: EF
graphics5.png is ‘n straal: CD

Twee lyne wat mekaar sny, vorm ‘n hoek.

Figure 3
Figure 3 (graphics6.png)

Ons noem die punt waar die twee lyne ontmoet, die hoekpunt.

Ons skryf: ABC

  • Het jy geweet?

Die eenheid waarin ons hoeke meet, is graad. Ons druk die grootte van‘n hoek in grade uit. ‘n Hoek van 60 grade skryf ons so: 60º.

Daar is ‘n paar soorte hoeke wat jy moet ken:

Table 2
Soorte hoeke
1. ‘n Omwenteling of volle draai is 360° groot. graphics7.png
2. ‘n Gestrekte hoek is ‘n halfdraai en is 180° groot. graphics8.png
3. ‘n Regte hoek is ‘n kwartdraai en is 90° groot. graphics9.png
4. ‘n Skerphoek is groter as 0°, maar kleiner as 90°. graphics10.png
5. ‘n Stomphoek is groter as 90°, maar kleiner as 180°. graphics11.png

AKTIWITEIT: Om hoeke te herken en te beskryf [LU 4.11]

1. Hoe goed ken jy nou jou hoeke?

Werk saam met ‘n maat en kyk of jy kan sê watter soort hoeke die volgende is:
