Example 1: Circumcircle
Task: Construct a triangle and its circumcircle.
Preparation
Open a new blank construction. Hide the Algebra view by tapping the arrow at the top. Hide the coordinate axes by tapping the axes icon in the Style Bar.
Steps
Choose the tool Polygon from the Toolbar. Now tap on the Graphics View three times to create the vertices A, B and C. Close the triangle by tapping point A again.
Next, tap the fourth icon from the left of the Toolbar and choose the tool Perpendicular Bisector. Construct two line bisectors by tapping on two sides of the triangle.
Using the tool Intersect Two Objects you can tap on the intersection of both line bisectors to get the center of your triangle’s circumcircle.
To finish your construction, choose the tool Circle with Center through Point and tap first on the center, then on any vertex of the triangle.
Using the Move tool you can now use your finger to drag the triangle vertices around - your construction will change dynamically with them.

Example 2: Quadratic Function
Task: Investigate the quadratic function f(x) = a x² + b using sliders for a and b.
Preparation
Open a new GeoGebra file. If the Algebra View is hidden, show it by tapping the arrow at the top.
Steps
Create the sliders a and b by selecting the tool Slider and tapping on the Graphics View. Choose a step size of 1.
Tap on the Input Bar and enter f(x) = a x² + b
Use the tool Move to change the value of the sliders a and b. Observe how the parabola changes dynamically.
Tap on the function graph to select it. Then change its color by using the Style Bar at the top left.
