Dessiner des figures géométriques
Préparations
- Choisir Dispositions – Géométrie.
Dessiner des images avec GeoGebra
Utilisez la souris et les outils suivants pour dessiner des figures dans la fenêtre Graphique (par ex. carré, rectangle, maison, arbre,…).
Nouveau point | |
Déplacer | |
Droite passant par deux points | |
Segment entre deux points | |
Effacer l'objet | |

Quelle pratique ?
- Comment sélectionner un objet déjà existant. Idée : Quand le pointeur survole un objet, il le met en surbrillance et change de forme, d'une croix, il devient une flèche. En cliquant vous sélectionner alors l'objet correspondant.
- Comment créer un point appartenant à un objet. Idée : Le point est affiché avec une couleur bleu clair. Toujours vérifier que le point appartient bien à l'objet en le déplaçant avec la souris.
- Comment corriger des erreurs pas à pas en utilisant les boutons Annuler et Refaire.
Idée : Plusieurs outils autorisent la création de points "à la volée". Aussi il n'est pas nécessaire que des points soient créés avant d'utiliser ces outils.
Exemple: L'outil Segment entre deux points peut être appliqués à deux points existant ou dans une fenêtre graphique vierge. En cliquant à deux endroits de la fenêtre graphique, les points correspondants sont créés et le segment les joignant est dessiné.
Sauvegarder des fichiers GeoGebra
Save your drawing
- Open the Menu Fichier and select Save.
- Select the folder GeoGebra_Introduction in the appearing dialog window.
- Type in a name for your GeoGebra file.
- Click Save in order to finish this process.
Idée : A file with the extension .ggb is created. This extension identifies GeoGebra files and indicates that they can only be opened with GeoGebra.
Idée : Name your files properly: Avoid using spaces or special symbols in a file name since they can cause unnecessary problems when transferred to other computers. Instead you can use underscores or upper case letters within the file name (e.g. First_Drawing.ggb).
What to practice
- How to open a new GeoGebra window using New Window from the Menu Fichier.
- How to open a blank GeoGebra interface within the same window (menu File – New) Idée : If you didn’t save the existing construction yet GeoGebra will ask you to do so before the blank screen is opened.
- How to open an already existing GeoGebra file (menu File – Open).
- Navigate through the folder structure in the appearing window.
- Select a GeoGeoGebra file (extension ‘.ggb’).
- Click Open.
Rectangle Construction
Preparations
- Summarize the properties de a rectangle before you start the construction.
- Open new GeoGebra file.
- Switch to Menu Dispositions - Géométrie de base.
- Change the labeling setting to New Points Only (menu Options – Labeling).
Introduction de New Outils
- Perpendicular Line and Parallel Line OutilsIdée : Click on an already existing line and a point in order to create a perpendicular line/parallel line through this point.
- Outil Intersection entre deux objets Idée : Click on the intersection point de two objets to get this one intersection point. Successively click on both objets to get all intersection points.
- Outil Polygone Idée : Click on the Graphique or already existing points in order to create the vertices de a polygon. Connect the last and first vertex to close the polygon! Always connect vertices counterclockwise!
Idée : Don’t forget to read the Outilbar help if you don’t know how to use a Outil.
Idée : Try out all new Outils before you start the construction.
Construction Steps
Check your Construction
- Apply the drag test to check if the construction is correct.
- Show the Navigation bar for construction steps (Menu Affichage) to review your construction step-by-step using the buttons.
- Show the Protocole de construction (Menu Affichage) and use it to review your rectangle construction step-by-step.
- Try to change the order de some construction steps by dragging a line with the mouse. Why does this NOT always work?
- Group several constructions steps by setting breakpoints:
- Show the column Breakpoint (Right click on the construction protocol window Columns - Breakpoint)
- Group construction steps by checking the Breakpoint box de the last one de the group
- Change setting to Show Only Breakpoints (Right click on the construction protocol window Options – Show Only Breakpoints)
- Use the navigation bar to review the construction step-by-step. Did you set the breakpoints correctly?
Equilateral Triangle Construction
Preparations
- Summarize the properties de an equilateral triangle before you start the construction.
- Open a new GeoGebra window.
- Hide Algèbre, Saisie and coordinate axes (Menu Affichage).
- Change the labeling setting to New points only (menu Options – Labeling).
Introduction de New Outils
- Outil Cercle (centre-point) Idée : First click creates center, second click determines radius de the circle.
- Outil Afficher/cacher l'objet Idée : Highlight all objets that should be hidden, then switch to another Outil in order to apply the visibility changes!
- Outil Angle Idée : Click on the points in counterclockwise direction! GeoGebra always creates angles with mathematically positive orientation.
Idée : Don’t forget to read the Outilbar help if you don’t know how to use a Outil.
Idée : Try out all new Outils before you start the construction.
Construction Steps
Check your Construction
- Apply the drag test to check if the construction is correct.
- Show the navigation bar or use the Protocole de construction to review your construction step-by-step.
Use the Dialogue_Propriétés to Enhance your Construction
There are different ways to access the Dialogue_Propriétés:
- Right-click (MacOS: Ctrl-click) an objet
- Select objet Properties… from the Menu Éditer
- Double click an objet in move mode
- Toggle Styling Bar on the right hand side de the Graphique
What to practice…
- Select different objets from the listeeeeeee on the left hand side and explore the available properties tabs for different types de objets
- Select several objets in order to change a certain property for all de them at the same time Idée : Hold the Ctrl-key (MacOS: Open Apple-click) pressed and select all desired objets.
- Select all objets de one type by clicking on the corresponding heading.
- Show the value de different objets and try out different label styles.
