This example demonstrates how to obtain a rectangle, square, and rhombus by modifying the length or angle of diagonals. Key mathematical concepts include properties of parallelograms, rectangles, and squares. GeoGebra commands used include Mirror, Segment, Polygon, and Angle. Suitable for middle school and above students to learn geometric transformations and properties.

GeoGebra Commands & Parameters

  1. Mirror(A, O) → C
  2. Segment(A, C) → d_p1
  3. Mirror(B, O) → D
  4. Segment(B, D) → d_p2
  5. Polygon(A, B, C, D) → poly1, a_1, b_1, c, d
  6. Angle(A, O, B) → β

AI Drawing Prompt Reference

Draw a parallelogram ABCD, then mirror point A and B around point O to get points C and D, connect point A and C to form diagonal d1, connect point B and D to form diagonal d2, and use points A, B, C, and D to form quadrilateral poly1. Measure the angle ∠AOB to get angle β.
