Rectangle Construction Practice: Using Segments

① This example demonstrates how to construct a rectangle in GeoGebra using the segment tool, starting from given points A and B, and verifying the construction. ② The core mathematical concepts involve the definition and properties of a rectangle: opposite sides parallel and equal, all angles right angles, and the rigor of geometric construction. ③ Construction highlights: based on the construction summary, the Segment command is used to create segments, involving objects such as wellDone (likely for checking completion), points A and B, and a function f (possibly for auxiliary verification or constraints). The steps likely include: drawing segment AB, constructing perpendicular or parallel lines, then connecting to form a rectangle, and using a condition (e.g., wellDone) to confirm correctness. ④ Suitable for middle school geometry beginners or GeoGebra introductory practice, helping students understand the geometric logic of rectangle construction and develop skills in dynamic geometry software.
