A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

##### What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

##### Who can create a lens?

Any individual member, a community, or a respected organization.

##### What are tags?

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

# Om hoeke te herken en te beskryf

Module by: Siyavula Uploaders. E-mail the author

## Memorandum

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

Konstant ewe ver van mekaar.

1. A: Ja

B: Ja

2. C

AKTIWITEIT 1.1

1.1 Stomphoek

1.2 Regtehoek

1.3 Omwenteling

• Skerphoek

KOPKRAPPER

2. Klasbespreking

## 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:

1. Is EF en GH ewewydig aan mekaar in:

A: __________________________________________________________________

B: __________________________________________________________________

2. Is C of K die verlenging van F?

Onthou jy nog?

 is ‘n lyn: AB is ‘n lynstuk: EF is ‘n straal: CD

Twee lyne wat mekaar sny, vorm ‘n hoek.

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:

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

## 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:

 1.1 _________________________________ 1.2 _________________________________ 1.3 _________________________________ 1.4 _________________________________

### Assessering

Leeruitkomste 4:Die leerder is in staat om gepaste meeteenhede, instrumente en formules in ‘n verskeidenheid kontekste te gebruik.

Assesseringstandaard 4.11: Dit is duidelik wanneer die leerder hoeke in twee-dimensionele vorms, drie-dimensionele voorwerpe en in die omgewing herken en beskryf.
