This example demonstrates finding the side length with a 3-digit square root. Key math concepts include square roots and addition. Using GeoGebra commands like Polygon and Text, a geometric figure is constructed. Suitable for middle school and above students learning geometric construction.

GeoGebra Commands & Parameters

  1. Polygon((0, 0), (0, 10), (10, 10), (10, 0)) → Tot, f, g, h, i
  2. Polygon((0, 0), (((10 / side * 100) * c), 0), 4) → C
  3. Polygon((((10 / side * 100) * c), 0), ((10 / side * ((100 * c) + (10 * d))), 0), ((10 / side * ((100 * c) + (10 * d))), ((10 / side * 100) * c)), (((10 / side * 100) * c), ((10 / side * 100) * c))) → Dl, j, k, l, m
  4. Polygon((0, ((10 / side * 100) * c)), (0, (10 / side * ((100 * c) + (10 * d)))), (((10 / side * 100) * c), (10 / side * ((100 * c) + (10 * d)))), (((10 / side * 100) * c), ((10 / side * 100) * c))) → Dt, n, p, q, r
  5. Polygon((((10 / side * 100) * c), ((10 / side * 100) * c)), ((10 / side * ((100 * c) + (10 * d))), ((10 / side * 100) * c)), 4) → Dc
  6. Polygon(((10 / side * ((100 * c) + (10 * d))), 0), (10, 0), (10, ((10 / side * 100) * c)), ((10 / side * ((100 * c) + (10 * d))), ((10 / side * 100) * c))) → Ul, s, t, a, b
  7. Polygon((0, (10 / side * ((100 * c) + (10 * d)))), (0, 10), (((10 / side * 100) * c), 10), (((10 / side * 100) * c), (10 / side * ((100 * c) + (10 * d))))) → Ut, e, f_1, g_1, h_1
  8. Polygon(((10 / side * ((100 * c) + (10 * d))), ((10 / side * 100) * c)), (10, ((10 / side * 100) * c)), (10, (10 / side * ((100 * c) + (10 * d)))), ((10 / side * ((100 * c) + (10 * d))), (10 / side * ((100 * c) + (10 * d))))) → Ulc, i_1, j_1, k_1, l_1
  9. Polygon((((10 / side * 100) * c), (10 / side * ((100 * c) + (10 * d)))), (((10 / side * 100) * c), 10), ((10 / side * ((100 * c) + (10 * d))), 10), ((10 / side * ((100 * c) + (10 * d))), (10 / side * ((100 * c) + (10 * d))))) → Utc, m_1, n_1, p_1, q_1
  10. Polygon(((10 / side * ((100 * c) + (10 * d))), (10 / side * ((100 * c) + (10 * d)))), (10, (10 / side * ((100 * c) + (10 * d)))), 4) → Ucc
  11. Text((100 * c), (((5 / side * 100) * c), -0.5)) → texto1
  12. Text((10 * d), ((10 / side * ((100 * c) + (5 * d))), -0.5)) → texto2
  13. Text(u, ((10 / side * ((100 * c) + (10 * d) + u / 2)), -0.5)) → texto3

AI Drawing Prompt Reference

Draw a 10x10 square, then construct a smaller square inside it with side length equal to 100 times c plus 10 times d. Add labels at each vertex to mark the values of c, d, and a variable u. Ensure all sides of the smaller squares are parallel to the sides of the larger square.
