This example demonstrates the relationship between a square and square root. Key mathematical concepts include the properties of a square and the calculation of square roots. Using GeoGebra commands such as Circle, Point, Segment, and Polygon, a square is constructed and its side length and area are calculated. Suitable for middle school and above students to learn geometry and algebra.

GeoGebra Commands & Parameters

  1. Circle(A, side) → c
  2. Point(c) → B
  3. Segment(B, A) → f
  4. OrthogonalLine(A, f) → g
  5. Intersect(c, g, 1) → C
  6. OrthogonalLine(C, g) → h
  7. OrthogonalLine(B, f) → i
  8. Intersect(h, i) → D
  9. Polygon(D, B, A, C) → poly1, d, b, a_1, c_1
  10. Segment(C, B) → j
  11. Midpoint(j) → E
  12. Midpoint(d) → F
  13. Midpoint(b) → G
