This example demonstrates the construction of a trapezium. It involves key mathematical concepts such as polygons and geometric construction. Using GeoGebra commands like Line, Point, LineBisector, OrthogonalLine, Intersect, Segment, a trapezium can be constructed. Suitable for middle school and above students to learn geometric construction.
