Sum of Line Segments

This example demonstrates how to construct and calculate the sum of lengths of two line segments using GeoGebra. Core mathematical concepts include line segment length calculation, algebraic equations, indefinite integral, inequalities, and intersection determination. Key GeoGebra commands and objects used are Segment for A-B, C-D, function definitions f, g, and calculations involving A_1, D_1, h, A_2, B_2, f_2, C_2, C_3, D_2, g_2, i, with text1 for result display. Suitable for high school mathematics teaching, illustrating the application of functions, integrals, and inequalities in geometric problems.
