1. Open the Geogebra.[br][br]2. Show the coordinate system and major gridlines.[br][br]3. Construct a slider with the fixed value of 54. ( It represents the circumference of the circle that we will construct.)[br][br]4. Put a point on the intersection point of x and y axis.[br][br]5. Use this point and the slider to construct a circle.[br][br]6. Construct a vector with any 2 points on x-axis to place the runner figures on the moving points.[br][br]7. Put two points on the circle representing the runners. ( F and G)[br][br]8. Use the vector translation to translate runner points to the left and right. These left and right points will [br]be used for placing the runner figures.[br][br]9. Construct a slider to show the change in velocity of runner 1. Do the same for runner 2. [br][br]10. Set the values of the sliders from 0 to 12 and increasing rate for the first runner will be 1 and for the runner 2, it will be 2.[br][br]11. Define the circumference of the circle as 2.r.(pi).[br][br]12. Take the intersection points between circle and y-coordinate.[br][br]13. Create a button to start animation and write AnimasyonuBaslat(F,G)[br][br]14. Create a button to stop animation and write AnimasyonuBaslat(False)[br][br]15. Create a button to reset for runners to be the starting point and write DegeriVer(G,I) and DegeriVer(F,I). [br] (I:Reset point)[br][br]16. Finally download the pictures of runners that you prefer and drag them into the working page.[br][br]17. Match the picture points with the points that mentioned in step 8.[br][br]18. Youır game is ready![br][br]19. ENJOY!
