Length of Line Segments

①This example demonstrates how to construct line segments in GeoGebra and measure their lengths, providing a visual representation of distances between geometric objects. ②Core mathematical concepts include line segments, length measurement, unit circle, definite integral, prism, and arithmetic mean, linking geometry with algebra. ③Construction highlights: using the Segment command with objects A, B, C, D, E, F and auxiliary objects f, g, h, building figures through points and segments, and displaying length values via measurement tools. ④Suitable for middle school geometry lessons or math lab activities, helping students understand segment length calculation and geometric construction visualization, also useful for exploring concepts like unit circle and integrals.
