Net and Surface Area of Trapezoidal Prism

This GeoGebra example demonstrates the net (unfolded 2D pattern) and surface area calculation of a trapezoidal prism (a right prism with trapezoidal bases). It covers core concepts in solid geometry: prism nets, surface area computation, and the Pythagorean theorem (used to find slant heights or diagonal lengths). The construction uses GeoGebra commands such as Polygon to create the trapezoidal bases and rectangular lateral faces, Segment for edges, and Intersect/Midpoint to define key vertices and midpoints. Objects like α, a, h, b, hyp represent dimensions and heights, allowing dynamic adjustment to explore how the net and surface area change. Suitable for middle and high school students learning solid geometry, surface area, and Pythagorean theorem applications, as well as for teacher demonstrations or student self-exploration.
