2020-03-10 00:04
This GeoGebra applet demonstrates the solution and geometric meaning of the absolute value inequality |x| > a. It shows the dynamic solution set (x > a or x < -a) as parameter a varies. Using Segment and If commands, it illustrates the interval representation on the real number line, helping students grasp the distance concept of absolute value and inequality solving logic.
