This worksheet demonstrates the construction of an isosceles trapezoid. Key mathematical concepts include the properties of isosceles trapezoids and geometric construction. Using GeoGebra commands such as Line, LineBisector, Point, Ray, Segment, Mirror, and Polygon, an isosceles trapezoid can be constructed. Suitable for middle school and above students or teachers.
