① This example demonstrates the geometric construction and area calculation of a kite and a rhombus. ② Core concepts include the quadrilateral area formula, perpendicular bisecting diagonals, and coordinate/vector methods for polygon area. ③ Construction highlights: Segment, Point, OrthogonalLine, Circle, Intersect, Polygon, PointIn, Midpoint commands create vertices A, B, C, D, E, F and polygon poly1 with label Textpoly1. ④ Suitable for middle‑school geometry lessons, high‑school analytic geometry review, and introductory GeoGebra workshops.
