GeoGebra Tutorial - 6 Triangle and Angles

In this tutorial we will construct a triangle and measure its internal angles.

• Click on File Menu and select New. (This will open a new GeoGebra window)
• Click on the drop down arrow of the Line through Two Points and choose the Segment between Two Points button

                             

• Construct a triangle using Segment between Two Points button. You will see in the Algebra Window , the three segments (sides of triangle) are represented by their lengths.

• To see which length corresponds to which side , click on the Move Tool (arrow) and hover the mouse over one of the sides to see the corresponding length light up.
• Now to measure internal angles of the triangle , select the Angle Button        and click once on vertices B , A and C in that order. This will give you measure of ∠BAC. (Make sure that you select the vertices in clockwise direction. Anti-clockwise selection will give you reflex angle.

• Similarly, measure ∠CBA and ∠ACB.
•  Now, drag the vertices using Move Button (Arrow). If you drag enough, you will notice reflex angles appearing. To stop this, right click on an angle in Algebra or Geometry Window, and choose Object Properties.Under Basic Tab un-check the Allow Reflex Angle check box and close the Object Properties box.

• Check your settings have been applied by dragging the vertices of your triangle.

GeoGebra Tutorial - 5 Translating Functions

In this tutorial we will see how the equation of a function changes dynamically when we drag its graph.

• Click on File Menu and select New. (This will open a new GeoGebra window)
• Click in the Input Field and type f(x) = x³
• Drag the curve around to see that its equation changes dynamically

After Translation

GeoGebra Tutorial - 4 Moving the Screen

GeoGebra allows you to move our construction around into a better position. To do this we use the Move Drawing Pad button 

• Click on the Move Drawing Pad button and use the left mouse button to drag the screen around. 
• Click on the Move Button when moving drawing pad is complete. 
• Click on the Undo Button (arrow mark on the upper right corner) to move back to the last position. If you keep clicking, it will return to the original position.

Tip : Hold down the Ctrl key and use the left mouse button to move the screen around. This will save a few clicks.
